QRF0620R30

Overview

The Powerex QRF0620R30 is a super fast recovery dual diode module rated for 600V repetitive peak reverse blocking voltage and 140A DC current at 80°C case temperature. It features a maximum reverse recovery time of 120ns and a typical on-state voltage of 1.8V at 140A. The device provides 2500V isolation between the circuit and baseplate, with a thermal resistance from junction to case of 0.205°C/W per diode.

Feature Summary

• Super fast recovery time for high-speed switching applications
• Isolated mounting design allows easy integration on common heatsinks
• Metal baseplate construction ensures low thermal impedance
• RoHS compliant manufacturing process

Applications

• Free wheeling circuits
• Welding machines
• Plasma cutting machines

Procurement Notes

Verify the specific suffix 'QRF' corresponds to the required pinout configuration among the QR series variants. Confirm that the application environment remains within the specified -40°C to 150°C operating junction temperature range. Ensure mounting torque does not exceed 26 in-lb for M6 screws or 17 in-lb for terminal screws to maintain mechanical integrity.

Selection Notes

Select this module when applications require fast recovery characteristics with moderate current handling capabilities. The dual diode configuration supports bridge or freewheeling topologies. Consider the 2500V isolation rating for safety requirements in industrial equipment. Evaluate thermal management needs based on the 0.205°C/W junction-to-case resistance.

Part Context

This component belongs to the Powerex Super Fast Recovery Dual Diode Module family. The QR series includes variants like QRD, QRC, and QRJ with different internal configurations. These modules are designed for robust performance in power conversion systems requiring reliable switching and thermal stability.

Replacement Considerations

Check datasheets for other QR series parts such as QRD0620R30 or QRC0620R30 to verify pin compatibility and electrical equivalence before substitution.
