* 2.3 Order of precedence. In the event of a conflict between the text of this document and the references cited
herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable laws
and regulations unless a specific exemption has been obtained.
3. REQUIREMENTS
* 3.1 General. The individual item requirements shall be as specified in MIL-PRF-19500 and as modified herein.
* 3.2 Qualification. Devices furnished under this specification shall be products that are manufactured by a
manufacturer authorized by the qualifying activity for listing on the applicable qualified manufacturer’s list (QML)
before contract award (see 4.2 and 6.3).
3.3 Abbreviations, symbols, and definitions. Abbreviations, symbols, and definitions used herein shall be as
specified in MIL-PRF-19500.
3.4 Interface and physical dimensions. The interface and physical dimensions shall be as specified in
MIL-PRF-19500, and on figure 1 (TO-254AA) herein. Methods used for electrical isolation of the terminal feed
throughs shall employ materials that contain a minimum of 90 percent AL

(ceramic). Examples of such
construction techniques are metallized ceramic eyelets or ceramic walled packages. The US Government's
preferred system of measurement is the metric SI system. However, since this item was originally designed using
inch-pound units of measurement, in the event of conflict between the metric and inch-pound units, the inch-pound
units shall take precedence.

MIL-PRF-19500/616B
3.4.1 Lead formation and finish. Lead finish shall be solderable as defined in MIL-PRF-19500, MIL-STD-750, and
herein. Where a choice of lead finish or formation is desired, it shall be specified in the acquisition document (see
6.2). When lead formation is performed, as a minimum, the vendor shall perform 100 percent hermetic seal in
accordance with screen 14 of MIL-PRF-19500.
3.4.2 Polarity. Polarity and terminal configuration shall be in accordance with figure 1 herein.
3.5 Marking. Marking shall be in accordance with MIL-PRF-19500.
3.6 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance
characteristics are as specified in 1.3 and table I herein.
* 3.7 Electrical test requirements. The electrical test requirements shall be the subgroups specified in table I
herein.
3.8 Workmanship. Semiconductor devices shall be processed in such a manner as to be uniform in quality and
shall be free from other defects that will affect life, serviceability, or appearance.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a.
b.
c.
Qualification inspection (see 4.2).
Screening (see 4.3).
Conformance inspection (see 4.4).
4.2 Qualification inspection. Qualification inspection shall be in accordance with MIL-PRF-19500 and as specified
herein.
* 4.2.1 Group E qualification. Group E inspection shall be performed for qualification or re-qualification only. In
case qualification was awarded to a prior revision of the specification sheet that did not request the performance of
table II tests, the tests specified in table II herein that were not performed in the prior revision shall be performed on
the first inspection lot of this revision to maintain qualification (see 4.4.4 herein).

MIL-PRF-19500/616B
* 4.3 Screening ( JANS, JANTX, and JANTXV levels only). Screening shall be in accordance with appendix E,
table IV of MIL-PRF-19500 and as specified herein. The following measurements shall be made in accordance with
table I herein. Devices that exceed the limits of table I herein shall not be acceptable.

sealing lots using a random five piece sample from each lot to be plotted on the applicable X bar R chart. If a lot
exhibits an out of control condition, the entire lot shall be removed from the line and held for engineering evaluation
and disposition.
