STMicroelectronics : Fast, high-voltage rectifier STTH30ACS06W helps to cut losses in powerswitching applications


STTH30ACS06W rectifier: low reverse current

STMicroelectronics’ STTH30ACS06W is an ultra-fast, high-voltage rectifier which is suited to use as a boost diode, especially in air conditioning equipment for continuous-mode interleaved power factor correction.

The device, which benefits from ST’s Turbo 2 600V technology, is also intended for use as a freewheeling diode in power supplies and other power-switching applications.

Capable of switching extremely fast, the STTH30ACS06W also features a low reverse current, and as a result it helps the designer to keep switching and conduction losses to a minimum. Reverse recovery current in fast-switching conditions is specified as 7.8A at a forward current of 30A and a junction temperature of 125°C.

The rectifier is also notable for its low thermal resistance for which it is rated at 1.2°C/W, junction-to-case.
