STMicroelectronics BUL39D, an NPN bipolar junction transistor, offers a robust solution for high-voltage switching applications. This component features a 450V collector-emitter breakdown voltage and a continuous collector current capability of 4A, with a maximum power dissipation of 70W. The minimum DC current gain (hFE) is specified at 10 at 10mA collector current and 5V collector-emitter voltage. The saturation voltage (Vce Sat) is a maximum of 1.1V at 500mA collector current and 2.5A base current. With a low collector cutoff current of 100µA (max), it ensures efficient operation. The BUL39D is housed in a standard TO-220-3 through-hole package, suitable for mounting on printed circuit boards. The operating junction temperature range extends up to 150°C. This device finds application in power supply units, general-purpose switching, and industrial control systems.
