NOTES: 1. This value applies for tp 0.3 ms, duty cycle 10%.
2. Derate linearly to 150°C case temperature at the rate of 0.72 W/°C.
3. Derate linearly to 150°C free air temperature at the rate of 16 mW/°C.
4. This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, IB(on) = -0.4 A, RBE = 100 ,
VBE(off) = 0, RS = 0.1 , VCC = -20 V.
