BUX39 Description

Short technical summary and product information.

The BUX39 is an NPN planar silicon transistor designed for high current and high power handling capabilities, combined with high switching speed. Manufactured by Thomson-CSF, this device is suitable for applications such as switching-control amplifiers, power gates, switching regulators, power-switching circuits, converters, inverters, and control circuits. It can also be used for DC-RF amplifiers and power oscillators.

 

Key electrical specifications include a maximum collector current of 30A and a collector-emitter sustaining voltage of 90V. The transistor offers a maximum power dissipation of 120W and a thermal resistance junction-to-case of 1.46 °C/W. It features a fast turn-on time and high current capability.

 

The BUX39 is housed in a TO-204AA (TO-3) package, designed for through-hole mounting. The datasheet indicates a maximum junction and storage temperature range of -65 to 100°C and a lead temperature of 230°C for 10 seconds.

 

This transistor is noted as being in Semelab's maintenance series and is not recommended for new designs.
