Derate linearly to 150C case temperature at the rate of 0.92 W/C. Derate linearly to 150C free air temperature at the rate of 28 mW/C. 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.
