Lead temperature 3.2 mm from case for 10 seconds

NOTES: 1. This value applies for t_p≤ 0.3 ms, duty cycle ≤ 10%.

2. Derate linearly to 150°C case temperature at the rate of 0.72 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, I_B(on)= 0.4 A, R_BE= 100 Ω,

_BE(off)= 0, R_S= 0.1 Ω, V_CC= 20 V.
