Richardson Electronics Adds Fast/Powerful Diode Module



Powerex QRS061K001 -- Fast 600V / 1000A Single Free-Wheel Diode

This new 1000 Amp Free-Wheel Diode Module can be used to add increased free-wheeling diode capability across Powerex's standard IGBT product lines. The QRS061K001 high-current fast diode module was developed for use on 230 Volt AC lines (or 340 Volt DC lines) and has an average current rating of 420 Amps.

Applications for which the QRS061K001 has been designed include inverters, switching power supplies, choppers, welding power supplies, and high-frequency rectifiers. The device has an optimized thermal management system incorporating an AIN substrate with a copper base.

QRS061K001 features include:
  • 600V, 1000A Rating
  • Fast Recovery Time (150 ns Max.)
  • Isolated Package - 3KV RMS Isolation Voltage
  • Low Thermal Impedance (0.07 ºC/W, junction to case)

    Datasheets for the QRS061K001 are available now from Richardson Electronics, 1-800-737-6937 (North America); or find your local sales engineer worldwide at http://www.rell.com/RFPD.
