These values apply when the base-emitter diode is open circuited.
Derate linearly to 150°C case temperature at the rate of 0.64 W/°C.
Derate linearly to 150°C free air temperature at the rate of 16 mW/°C.
This rating is based on the capability of the transistor to operate safely in a circuit of: L = 20 mH, IB(on) = -5 mA, RBE = 100 Ω,
V BE(off) = 0, RS = 0.1 Ω, VCC = -20 V.
