This specification is approved for use by all Departments
and Agencies of the Department of Defense.
The requirements for acquiring the product described herein shall consist of
this specification sheet and MIL-PRF-19500.
1. SCOPE
1.1 Scope. This specification covers the performance requirements for a N-channel, enhancement-mode,
MOSFET, radiation hardened (Total Dose and Single Event Effects (SEE)), power transistor. Two levels of product
assurance are provided for each device type as specified in MIL-PRF-19500, with avalanche energy maximum rating
(EAS) and maximum avalanche current (IAS).
1.2 Physical dimensions. See figure 1, (surface mount, LCC-18).
