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, I
