The BU508AW is an NPN bipolar junction transistor (BJT) designed for high-voltage switching and amplification applications. Manufactured by STMicroelectronics, this device features a maximum collector-emitter voltage (Vceo) of 700V, a continuous collector current (Ic) rating of 8A, and a power dissipation (Pd) of 125W. The DC current gain (hFE) is a minimum of 10 at Ic=100mA and Vce=5V, and the collector-emitter saturation voltage (Vce(sat)) is 1V maximum at Ib=1.6A and Ic=4.5A.
The transistor is packaged in a standard TO-247-3 case, which is a through-hole mounting package suitable for applications requiring efficient heat dissipation. The maximum junction temperature is 150°C. While specific transition frequency data is not provided in the available specifications, the device is suitable for power switching and linear applications where high voltage and moderate current are required.
Typical applications include power supply circuits, motor control, and general-purpose switching. The RoHS status is listed as compliant (unverified), and the MSL (Moisture Sensitivity Level) is 1 (Unlimited). Caution: Compliance data is unverified and should be confirmed from official sources.
