The BUL49D is an NPN bipolar junction transistor by STMicroelectronics designed for high-voltage switching applications. It features a collector-emitter breakdown voltage of 450V and a continuous collector current rating of 5A, making it suitable for power switching circuits.
The device can dissipate up to 80W of power, with a minimum DC current gain of 4 at Ic=7A and Vce=10V. The collector-emitter saturation voltage is 1.2V maximum at Ib=800mA and Ic=4A, ensuring low conduction losses in saturated switch operation.
Packaged in a TO-220-3 through-hole package, the BUL49D is designed for easy mounting on printed circuit boards with effective heat sinking. The maximum junction temperature is 150°C, providing a reasonable thermal margin for power applications.
