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 requirements and physical dimensions shall be as specified
in MIL-PRF-19500, and figures 1, 2, 3, 4, and 5 herein.
* 3.4.1 Lead finish. 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).
* 3.5 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 paragraph 1.3, 1.4 and table I.
3.7 Electrical test requirements. The electrical test requirements shall be as specified in table I.
3.8 Electrostatic discharge protection. The devices covered by this specification require electrostatic discharge
protection.
3.8.1 Handling. MOS devices must be handled with certain precautions to avoid damage due to the accumulation
of static charge. However, the following handling practices are recommended.
a.
Devices should be handled on benches with conductive handling devices.
b.
Ground test equipment, tools, and personnel handling devices.
c.
Do not handle devices by the leads.
d.
Store devices in conductive foam or carriers.
e.
Avoid use of plastic, rubber, or silk in MOS areas.
f.
Maintain relative humidity above 50 percent if practical.
g.
Care should be exercised during test and troubleshooting to apply not more than maximum rated voltage to
any lead.
Gate must be terminated to source, R 100 k, whenever bias voltage is to be applied drain to source.
h.
3.9 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.
