90 W at 25°C Case Temperature
15 A Continuous Collector Current
Customer-Specified Selections Available
absolute maximum ratings at 25°C case temperature (unless otherwise noted)
NOTES: 1. This value applies when the base-emitter resistance RBE = 100 .
2. Derate linearly to 150°C case temperature at the rate of 0.72 W/°C.
3. Derate linearly to 15C free air temperature at the rate of 28 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 = -10 V.

NOTES: 5. These parameters must be measured using pulse techniques, tp = 300 µs, duty cycle 2%.
6. These parameters must be measured using voltage-sensing contacts, separate from the current carrying contacts.
Voltage and current values shown are nominal; exact values vary slightly with transistor parameters.
