The Powerex QRS061K001 600V/ 1000A free-wheel diode modules supplied by Richardson Electronics are now available from Wireless Components .  

The new 1000 Amp free-wheel diode modules can be used to add increased free-wheeling diode capability across Powerex’s standard IGBT product lines.  

The QRS061K001 high-current fast diode modules were developed for use on 230 Volt AC lines (or 340 Volt DC lines) and have an average current rating of 420 Amps.  

The QRS061K001 free-wheel diode modules find application in inverters, switching power supplies, choppers, welding power supplies and high-frequency rectifiers.  

The device has an optimised thermal management system incorporating an AIN substrate with a copper base.  

Key features of QRS061K001 free-wheel diode modules: 

  • 600V, 1000A rating
  • Fast recovery time (150 ns maximum)
  • Isolated package: 3KV RMS isolation voltage
  • Low thermal impedance (0.07ºC/W, junction to case)
