BUW48 Description

Short technical summary and product information.

The BUW48 is a high power NPN silicon transistor manufactured by STMicroelectronics. It is designed for high frequency and efficiency converters, motor control, and industrial equipment. The device is housed in a TO-218-3 through-hole package.

 

Key electrical specifications include a collector-emitter voltage (VCEO) of 60V, a collector-emitter voltage (VCEV) of 120V with Vbe=-1.5V, and an emitter-base voltage of 7V. The collector current is rated at 30A with a peak current of 45A. The total power dissipation is 150W at Tc=25°C, and the operating junction temperature can reach up to 175°C.

 

The BUW48 offers fast switching speeds with a transition frequency of 8 MHz and low saturation voltages, such as 0.6V at Ic=20A, Ib=2A. It is suitable for switching regulators and motor control applications.
