MECHANICAL STANDARDIZATION OF SEMICONDUCTOR DEVICES –
Part 4: Coding system and classification into forms of package
outlines for semiconductor device packages
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60191-4 has been prepared by subcommittee 47D: Semiconductor
devices packaging, of IEC technical committee 47: Semiconductor devices.
This third edition cancels and replaces the second edition published in 1999,
Amendment 1:2001 and Amendment 2:2002.This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Material code "S" is added to indicate a silicon based package.
b) Description of "WL" is added to be used for general use.

MECHANICAL STANDARDIZATION OF SEMICONDUCTOR DEVICES –
Part 4: Coding system and classification into forms of package
outlines for semiconductor device packages
1 Scope
This part of IEC 60191 specifies a method for the designation of package outlines and for the
classification of forms of package outlines for semiconductor devices and a systematic method
for generating universal descriptive designators for semiconductor device packages.
The descriptive designator provides a useful communication tool but has no implied control for
assuring package interchangeability.
2 Coding system of package outlines for semiconductor devices
The following coding system will be used in the publications concerning mechanical
standardization:
– first: a three-digit serial number (000 to 999);
– second: a single reference letter indicating the form as shown in Table 1;
– third: a two-digit serial number (00 to 99) to indicate a variant of an outline drawing.
The use of prefix P to indicate a provisional drawing remains unchanged.
Examples
– 101A00
– 050G13
– P 101F01
3 Classification into forms of package outlines for semiconductor devices
The package outline drawings for semiconductor devices are classified into forms according to
the following scheme:
– form A: single-ended
– form B: heat-sink-mounted
– form C: stud-mounted
– form D: axial-leaded
– form E: surface-mounted
– form F: single-ended, heat-sink-mounted
– form G: dual and quad in-line
– form H: axial lead-less.

4 Coding system for semiconductor-device packages
4.1 General
The standard coding system is a method for identifying the physical features of an electronic
device package family. The system is predicated upon a minimum two-character designator,
which indicates the package outline style. This designator can be extended, through the use of
optional, user-selected fields, to provide additional package information such as terminal
position and count, terminal form, package shape, and predominant body material.
4.2 New descriptive codes
If a new package that does not conform to one of the designated field character codes is being
proposed, a new code may be recommended for standardization.
4.3 Descriptive designators
4.3.1 General remarks
The package outline style code is the only compulsory field within this descriptive designation
system. Additional information may be provided using optional prefixes and suffixes described
by the system. In general, these fields are independent of one another. Unless otherwise
indicated herein, the users of this system may pick and choose which of these fields they wish
to implement for their specific application (see Figure 1). The descriptive designator may be
extended with additional information, provided this information is separated from the
descriptive designator by a slash (/) (see 4.3.7).
NOTE Basic package codes and names are presented in Table B.1.
4.3.2 Minimum descriptive designator
The minimum descriptive designator is a two-letter code that classifies device packages into
standard package outline styles. These styles identify general external physical features.
Common two-letter descriptive codes or abbreviations are included, such as CC, FP, SO, GA.
Figure A.1 shows two-letter codes for various device package outline styles and depicts
examples of each. Table 1 lists the two-letter package-outline-style codes described in
Clause 5.

* Industry practice sometimes uses "P" for "package" in the location normally occupied by this field (except that
there is no preceding hyphen), for example SOP.
4.3.3 Terminal-position prefix
The two-letter, package-outline-style code may be supplemented with a single-letter prefix that
identifies the physical terminal positions or, if applicable, the interconnect land pattern.
Examples of three-letter designators include common acronyms or abbreviations, such as DIP,
LCC (QCC preferred), PGA, QFP, SIP, ZIP.
NOTE 1 A terminal is defined as an externally available point of connection.
NOTE 2 The proper terminal-position prefix is determined by the interconnect land structure. For example, the
code for a single row of terminals formed into a staggered configuration would be "Z".
Table 2 gives a list of one-letter, terminal-position prefix codes.
4.3.4 Package-body-material prefix
The three-letter descriptive designator (see 4.3.2) may be further supplemented by a single-
letter prefix that identifies the predominant package-body material. This prefix shall not be
used unless the terminal-position prefix described in 4.3.2 is also used. Examples of such four-
letter descriptive designators include common acronyms or abbreviations, such as CDIP, PDIP,
PLCC (PQCC preferred), MELF, PQFP.
Table 3 gives a list of one-letter package-body-material prefix codes.
---------------------- Page: 12 ----------------------
SIST EN 60191-4:2014
60191-4 IEC:2013 – 9 –
If the package-body material is other than one of those defined in Table 3, the letter "X" shall
be used within the descriptive designator to signify a special or new material and shall later be
replaced with an IEC-approved code.
4.3.5 Package-specific feature prefix
Package-specific features may be described through the use of a multiletter prefix. The
package-specific feature prefix shall be set off from the following portion of the descriptive
designator by a dash (–).
Table 4 gives a list of package-specific feature prefix codes. Figure 2 shows the relationship of
codes to profile and pitch.
4.3.6 Lead-form and terminal-count suffixes
4.3.6.1 General lead-form and number of terminals
The general lead form (or terminal shape) and/or the number of terminals on a package may
be described through the use of two fields, the lead-form suffix and the terminal-count suffix.
These two fields shall be set off from the preceding portion of the descriptive designator by a
dash (–).
Users of this system may choose to use the lead-form suffix, or the terminal-count suffix, or
both. If the lead-form suffix is used in conjunction with the terminal-count suffix, it shall
precede the terminal-count suffix.

4.3.6.2 Lead-form suffix
The lead-form suffix is a one-letter suffix that identifies the standard form or shape of the lead.
Table 5 gives a list of one-letter, lead-form suffix codes.
If more than one type of terminal is present, the terminals carrying the principal current
determine the lead-form code. If one of these terminals is a mounting stud or flange, its shape

shall not govern the choice of lead-form (or terminal-shape) suffix because that has already
been described by the package-outline-style code. If the lead form is other than one of those
defined in Table 5, the letter "X" shall be used within the descriptive designator to signify a
special or new lead form and shall later be replaced with an IEC-approved code. Examples are
illustrated in Figure A.2.
4.3.6.3 Terminal-count suffix
The terminal-count suffix is a numeric field used to identify the number of terminals on the
device package. If there is more than one type of terminal, the terminal count shall include only
those terminals that were used to determine the lead-form suffix in accordance with 4.3.6.1. If
the terminal count (including terminals not used) is less than the number of available terminal
positions, the latter may be added in parentheses, for example 20(26) and 168(289).
4.3.7 Detailed information field
A slash (/), followed by a supplemental one- to twenty-character detailed information field, may
be added to the descriptive designator. The field may contain the IEC designation or some
other user-specified coding scheme.
The slash (/) shall signify the beginning of the supplementary detailed information field. There
shall be no space character between the slash (/) and adjacent fields.
