The STMicroelectronics BULD742CT4 is an NPN bipolar junction transistor designed for high voltage switching applications. It features a collector-emitter voltage rating of 400V and a continuous collector current capacity of 4A, making it suitable for power control circuits.
Key electrical characteristics include a power dissipation of 45W, a DC current gain of 25 minimum at 800mA collector current and 3V Vce, and a collector-emitter saturation voltage of 1.5V maximum at 1A base current and 3.5A collector current. The junction temperature rating is 150°C.
The device is offered in a surface mount DPAK (TO-252) package, which provides a compact footprint for automated assembly. The package is also compatible with the DPak (2 Leads + Tab) and SC-63 industry standards.
