BUV27 Description

Short technical summary and product information.

The BUV27 is a multiepitaxial planar NPN silicon transistor manufactured by STMicroelectronics, housed in a TO-220 package. It is designed for high frequency and efficiency converters, switching regulators, and motor control applications.

 

Key electrical specifications include a collector-base voltage of 240V, collector-emitter voltage of 120V, and emitter-base voltage of 7V. The device supports a continuous collector current of 12A with a peak current of 20A. Power dissipation is rated at 85W at case temperatures below 25°C and 65W below 60°C.

 

The transistor offers fast switching performance with typical turn-on time of 0.4µs and storage time of 0.5µs under resistive load conditions. Low collector-emitter saturation voltage of 0.7V at 4A collector current contributes to efficient operation in switching applications.

 

The BUV27 is mounted through-hole in a TO-220 package, suitable for PCB mounting with appropriate heat sinking. Maximum junction temperature is 175°C with thermal resistance of 1.76°C/W from junction to case.
