MIL-PRF-19500/384H
Adjust VCC and P1 for VCE = 100 V at IC = 350 mA.
VCC: 110 V, 1 amp capability, current limited, voltage regulated supply, ±1 percent line and load.
P1: Pulse current generator, 0 to +140 mA capability.
tp = 1 second, Test cycles = 1, TC = +25°C.
IC: Current indicator (meter or sampling resistor and oscilloscope) with voltage drop less than 1 V at 350
mA.
VCE: Voltage indicator with current requirement of < 1 mA at 100 V (oscilloscope, VTVM or high impedance
multimeter).
Reject criteria: Reject if second breakdown occurs, as indicated by collector current sudden increase and
becoming uncontrollable by P1.
