The onsemi BUH50 is a SWITCHMODE™ series NPN bipolar junction transistor designed for high-voltage switching applications. This through-hole component offers a 500 V collector-emitter breakdown voltage and a continuous collector current capability of 4 A. With a maximum power dissipation of 50 W and a transition frequency of 4 MHz, the BUH50 is suitable for power supply regulation and switching circuits. Key parameters include a Vce(sat) of 1 V at 3 A collector current with 1 A base current, and a minimum DC current gain (hFE) of 5 at 2 A collector current and 5 V collector-emitter voltage. This transistor, housed in a TO-220 package, finds application in general purpose power switching, lighting, and industrial motor control. It operates within an ambient temperature range of -65°C to 150°C.
