BUX87 ST Bipolar (BJT)

The BUX87 is an NPN bipolar power transistor from STMicroelectronics in SOT-32-3 (TO-126) through-hole package, featuring 450V collector-emitter voltage, 500mA continuous collector current, and 40W power dissipation. For selection, verify DC current gain (hFE) of 12 min at 40mA, collector-emitter saturation voltage of 1V at 200mA, transition frequency of 20MHz, and operating junction temperature up to 150°C. Features include high voltage capability for medium-power applications, rugged reliability, and through-hole SOT-32 package for robust mounting. Ideal for switching regulators, flyback converters in AC-DC adapters, relay drivers, solenoid controllers, and any 450V medium-power switching application requiring 500mA current capability.
