BU326S Description

Short technical summary and product information.

The BU326S is a silicon multiepitaxial NPN transistor manufactured by ST, housed in a Jedec TO-3 metal case. It is specifically designed for switch-mode CTV applications.

 

Key electrical characteristics include a collector-emitter voltage of 800V (V_BE=0) and 400V (I_B=0), a continuous collector current of 6A, and a peak collector current of 8A. The device also offers a maximum power dissipation of 60W at T_case < 75°C.

 

Thermal data indicates a junction-to-case thermal resistance of 1.67°C/W. The transistor operates within a storage temperature range of -65 to 175°C and has a junction temperature limit of 175°C.

 

Mechanical data specifies the TO-3 package with dimensions in millimeters. The collector is connected to the case.
