BD746, BD746A, BD746B, BD746C PNP SILICON POWER TRANSISTORS PRODUCT INFORMATION 1 AUGUST 1978 - REVISED MARCH 1997Copyright © 1997, Power Innovations Limited, UK Information is current as of publication date. Products conform to specifications in accordance with the terms of Power Innovations standard warranty. Production processing does not necessarily include testing of all parameters. lDesigned for Complementary Use with the BD745 Series l115 W at 25°C Case Temperature l20 A Continuous Collector Current l25 A Peak Collector Current lCustomer-Specified Selections Available SOT-93 PACKAGE (TOP VIEW) Pin 2 is in electrical contact with the mounting base. MDTRAA B C E 1 2 3 absolute maximum ratings at 25°C case temperature (unless otherwise noted) 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 0.92 W/°C. 3.Derate linearly to 150°C 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, I B(on) = -0.4 A, R BE = 100 Ω, V BE(off) = 0, R S = 0.1 Ω, V CC = -20 V.
