STMicroelectronics BULD741-1 is an NPN bipolar junction transistor (BJT) designed for general-purpose power switching applications. This through-hole component features a 400V collector-emitter breakdown voltage and a continuous collector current rating of 2.5A, with a maximum power dissipation of 30W. The IPAK package (TO-251AA) facilitates efficient heat management. Key electrical characteristics include a saturation voltage (Vce(sat)) of 1.5V at 2A collector current and 600mA base current, and a minimum DC current gain (hFE) of 25 at 450mA collector current and 3V Vce. This device is suitable for use in power supplies, lighting control, and motor drive circuits across various industrial and consumer electronics sectors.
