STMicroelectronics BUL705 NPN Bipolar Junction Transistor designed for robust power applications. This through-hole component, packaged in a TO-220-3 configuration, offers a 400V collector-emitter breakdown voltage and a continuous collector current capability of 5A, with a maximum power dissipation of 80W. Key parameters include a saturation voltage of 800mV at 1A base current and 4A collector current, and a minimum DC current gain (hFE) of 16 at 2A collector current and 5V collector-emitter voltage. The device features a collector cutoff current of 250µA and operates up to a junction temperature of 150°C. The BUL705 finds application in industrial control, power supplies, and automotive systems where reliable switching and amplification of power signals are critical.
