Outline

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.

Features

  • Lineup includes modules with various types of connections
  • The general rectifying diode modules are 400-2,000V/20-500V
  • Lineup includes the high-speed switching diode modules of 250-1,200V/20-450A (compatible with transistor modules and IGBT/IPM)
  • Complies with the RoHS directive
  • Some products available for snubber circuits.
