1 / 5 page BD249, BD249A, BD249B, BD249C NPN SILICON POWER TRANSISTORS P R O D UCT INFORMA TION 1 JUNE 1973 - REVISED SEPTEMBER 2002 Specifications are subject to change without notice. ● Designed for Complementary Use with the BD250 Series ● 125 W at 25°C Case Temperature ● 25 A Continuous Collector Current ● 40 A Peak Collector Current ● Customer-Specified Selections Available 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 1 W/°C. 3. Derate linearly to 150°C free air temperature at the rate of 24 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.
