BU326 Description

Short technical summary and product information.

The BU326 is a silicon NPN power transistor manufactured by Thomson-CSF. It is designed for high voltage and high speed operation, featuring a low collector saturation voltage. This transistor is intended for use in the chopper supplies of CTV receivers.

The BU326 comes in a TO-3 package and offers a collector-base voltage of up to 800V (BU326) or 900V (BU326A) and a collector-emitter voltage of up to 375V (BU326) or 400V (BU326A). It can handle a continuous collector current of 6A and a peak collector current of 8A. The total power dissipation is rated at 75W at 25°C case temperature.

Key electrical characteristics include a DC current gain (hFE) of at least 25 at 1A/5V and a transition frequency (fT) of 4MHz at 0.2A/10V. Switching times are also specified, with a turn-on time of 0.5µs, storage time of 3.5µs, and fall time of 0.5µs under specific test conditions.

The operating temperature range for the junction is from -65°C to 200°C, and the storage temperature range is also -65°C to 200°C. The thermal resistance from junction to case is 2.33°C/W.
