absolute maximum ratings at 25°C case temperature (unless otherwise noted)
NOTES: 1. This value applies for tp ≤ 0.3 ms, duty cycle ≤ 10%.
2. Derate linearly to 150°C case temperature at the rate of 0.52 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.

Specifications are subject to change without notice.
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.
