DC Tests: TC= +25 °C, 1 Cycle, t = 1.0 s (See Figure 3 of MIL-PRF-19500/371)

Test 1: VCE = 28.6 Vdc, IC= 3.5 Adc

Test 2: VCE = 70 Vdc, IC= 1.43 Adc

TEST 3: VCE = 325 Vdc, IC= 55 mAdc 2N3902

VCE = 400 Vdc, IC= 35 mAdc 2N5157

Switching Test:

Load condition C (unclamped inductive load)

TC= 25°C, duty cycle < 10%; RS= 0.1 Ω(See Figure 4 of MIL-PRF-19500/371)

Test 1: tP = approximately 3 ms (vary to obtain IC), RBB1 = 20 Ω, VBB1 = 10 Vdc; RBB2 = 3 kΩ,

VBB2 = 1.5 Vdc, VCC = 50 Vdc, lC= 3.5 Adc, L = 60 mH, R = 3 Ω; RL<14 Ω

Test 2: tP = approximately 3 ms (vary to obtain IC), RBB1 = 100 Ω, VBB1 = 10 Vdc; RBB2 = 3 kΩ,

VBB2 = 1.5 Vdc, lC= 0.6 Adc, VCC = 50 Vdc, L = 200 mH, R = 8 Ω; RL<83 Ω

Switching Tests:

Load condition (clamped inductive load)

TC= 25°C, duty cycle < 10% (See Figure 5 of MIL-PRF-19500/371)

Test 1: tP = approximately 30 ms (vary to obtain IC), RS= 0.1 Ω, RBB1 = 20 Ω, VBB1 = 10 Vdc;

RBB2 = 100 Ω, VBB2 = 1.5 Vdc, VCC = 50 Vdc, lC= 3.5 Adc, L = 60 mH, R = 3 Ω; RL<0 Ω
