MIL-PRF-19500/404C
NOTES:
1. Oscilloscope-rise time < 7 ns; input impedance = 1 MΩ; 22 pF.
2. Pulse generator - rise time < 10 ns; source impedance = 50Ω.
3. Recovery time shall be measured on the above circuit and with equipment as shown. The pulse generator shall have a pulse
repetition frequency of 1 kHz and a pulse width of 200 ns recovery conditions 125 mA forward current to .250 mA reverse current.
Recovery time measured when rectifier recovers to 63 mA.
