Bourns Inc. BD746-S is a PNP bipolar junction transistor designed for high-current applications. This component features a collector-emitter breakdown voltage (Vce) of 45 V and a maximum continuous collector current (Ic) of 20 A. The minimum DC current gain (hFE) is specified as 20 at 5 A collector current and 4 V Vce. It offers a power dissipation of 3.5 W and a saturation voltage (Vce(sat)) of 3 V at 5 A base current and 20 A collector current. The transistor is housed in a SOT-93 (TO-218-3) through-hole package suitable for robust mounting. Operating temperature ranges from -65°C to 150°C. This device finds application in power management and switching circuits within industrial automation and consumer electronics.
