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 Ω, VBE(off) = 0, RS = 0.
1 Ω, VCC = 20 V.
