The BU508AF is an NPN bipolar junction transistor manufactured by STMicroelectronics. It features a minimum collector-emitter breakdown voltage of 700V and a maximum collector current of 8A, making it suitable for high-voltage switching applications. The device can dissipate up to 50W of power and operates at a maximum junction temperature of 150°C.
Electrical characteristics include a DC current gain (hFE) of at least 10 at Ic=100mA and Vce=5V, and a maximum collector-emitter saturation voltage of 1V at Ib=1.6A and Ic=4.5A. These parameters support efficient switching performance in linear and switching circuits.
The transistor is housed in a TO-3P-3 Full Pack (TO-3PF) through-hole package, which provides robust thermal management and mechanical stability. The through-hole mounting type is suitable for traditional PCB assembly processes.
