Bourns Inc. BD249B-S is an NPN bipolar junction transistor (BJT) designed for robust power applications. This component features a collector-emitter breakdown voltage (Vce) of 80 V and a continuous collector current (Ic) rating of up to 25 A. The BD249B-S offers a minimum DC current gain (hFE) of 10 at 15 A and 4 V. With a maximum power dissipation of 3 W, it is suitable for demanding environments. The transistor is housed in a SOT-93 (TO-218-3) package for through-hole mounting, ensuring efficient heat dissipation. Typical applications include power switching, linear voltage regulation, and amplification circuits, commonly found in industrial automation, power supplies, and motor control systems. The operating temperature range is -65°C to 150°C.
