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 PNPN, silicon power, reverse-blocking
triode thyristors. Three levels of product assurance are provided for each device type as specified in
1.2 Physical dimensions. See figure 1 (similar to TO-64).
1.3 Maximum ratings. Unless otherwise specified, TA = +25°C.

This average forward current is for a maximum case temperature of +105°C, and 180 electrical degrees of
(1)
conduction.
(2)
Surge rating is non-recurrent and applies only with device in the "on" conducting state. The peak rate of
surge current must not exceed 40 amperes/microsecond during the first 10 µs after switching from the "off"
(blocking) state to the "on" (conducting) state. This time is measured from the point where the thyristor
voltage has decayed to 90 percent of its initial blocking value.
TC = -65°C to +150°C.
