The BUV48 from Thomson-CSF is a multiepitaxial mesa NPN transistor designed for high voltage switching applications, particularly those directly connected to 220V and 380V mains. It is available in three package types: TO-3 metal case, TO-218 plastic package, and the fully isolated ISOWATT218 package.
Key electrical characteristics include a collector-emitter voltage (Vces) of up to 1000V and a continuous collector current (Ic) of 15A. The transistor also offers a high collector peak current capability of 30A (tp < 5ms) and non-repetitive peak current of 55A (tp < 20µs). Its switching characteristics include a turn-on time of 1µs and a fall time of 0.8µs under specified test conditions.
Thermal performance varies by package. The TO-3 package offers a total power dissipation of 175W at 25°C and a junction-to-case thermal resistance of 1°C/W. The TO-218 package has a power dissipation of 125W and the same thermal resistance, while the ISOWATT218 package has a power dissipation of 65W and a thermal resistance of 1.92°C/W. The maximum operating junction temperature is 200°C for the TO-3 package and 125°C for the TO-218 and ISOWATT218 packages.
This transistor is suitable for power supply circuits, inverters, and other applications requiring robust high-voltage switching. Its availability in different packages allows for flexibility in design and thermal management.
