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 and as follows:
I
AS
- Rated avalanche current, nonrepetitive
nC - nano Coulomb
3.4 Interface and physical dimensions. Interface and physical dimensions shall be as specified in
MIL-PRF-19500, and on figure 1 (TO-205AF).
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. At the option of the manufacturer, marking of
the country of origin may be omitted from the body of the transistor but shall be retained on the initial container.
3.6 Electrostatic discharge protection. The devices covered by this specification require electrostatic discharge
protection.

accumulation of static charge. However, the following handling practices are recommended (see 3.6).
a.
b.
c.
d.
e.
f.
g.
Devices should be handled on benches with conductive handling devices.
Ground test equipment, tools, and personnel handling devices.
Do not handle devices by the leads.
Store devices in conductive foam or carriers.
Avoid use of plastic, rubber, or silk in MOS areas.
Maintain relative humidity above 50 percent if practical.
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
≤
or 100 kΩ, whenever bias voltage is applied drain to source.
