Radiation hardness assurance

JANSR2ST3360K is guaranteed at 100 krad in compliance with the MIL-PRF-19500 Group D between 50 and

300 rad/s and 0.1 rad/s as per ESCC 22900. Post radiation electrical characteristics are described in Table 5 and

Table 6.

1. Pulsed duration = 300 μs, duty cycle ≥ 2 %

2. See method 1019 of MIL-STD-750 about how to determine [hFE] by first calculating the delta (1/hFE) from the pre- and

post-radiation hFE. Note that the [hFE] is not the same as hFE and cannot be measured directly. The [hFE] value can never

exceed the pre-radiation minimum hFE, which is based upon.
