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. The abbreviations, symbols, and definitions used herein shall be as

specified in MIL�PRF�19500 and as follows:

�

The measurement current applied to forward bias the junction for measurement of VBE.

�

The collector current applied to the device under test during the heating period.

�

The duration of the applied heating power pulse.

tSW

�

Sample window time during which final VBE measurement is made.

3.4 Interface and physical dimensions. The interface and physical dimensions shall be as specified in

3.4.1 Lead finish. The lead finish shall be solderable in accordance with MIL�PRF�19500, MIL�STD�750, and

herein. Where a choice of lead finish is desired, it shall be specified in the acquisition document (see 6.2).

3.4.2 Polarity. The identification of terminals of the device package shall be as shown on figure 1. Terminal 1

shall be connected to the base, terminal 2 shall be connected to the emitter, and the collector shall be electrically

connected to the case.

3.5 Electrical performance characteristics. Unless otherwise specified herein, the electrical performance

characteristics are as specified in 1.3, 1.4, and table I herein.

3.6 Electrical test requirements. The electrical test requirements shall be as specified in table I.

3.7 Marking. Marking shall be in accordance with MIL�PRF�19500.

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:

Qualification inspection (see 4.2).

Screening (see 4.3).

Conformance inspection (see 4.4 and tables I and II).

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.
