We offer general rectifying diode modules that rectify commercial frequencies and high frequency diode modules for freewheel diodes in inverter circuits and for high-speed switching on a surge voltage absorbing circuit (snubber).
The main switching devices of an inverter have changed from bipolar transistors to high-speed MOS gate devices, such as IGBT. The requirements of radio noise regulations have also increased the importance of not just reverse recovery characteristics, but also software recovery characteristics.
