Quality Control: Learn More
onsemi's BUL45D2 is an NPN bipolar junction transistor designed for high-voltage switching applications. This component features a 400V collector-emitter breakdown voltage (Vce max) and a continuous collector current capability of 5A. With a power dissipation of 75W, it is suitable for demanding power supply and control circuits. The device exhibits a minimum DC current gain (hFE) of 10 at 2A and 1V, and a transition frequency of 13MHz. Its saturation voltage (Vce sat) is specified at a maximum of 500mV at 400mA base current and 2A collector current. The BUL45D2 is provided in a standard TO-220-3 package for through-hole mounting, ensuring robust thermal performance and ease of assembly in industrial power control, lighting, and motor drive systems.
