QRF0630R30

Overview

The Powerex QRF0630R30 is a super fast recovery dual diode module rated for 210 Amperes and 600 Volts. It features a metal baseplate with isolated mounting, allowing installation on common heatsinks. The device provides 2500V isolation voltage between the circuit and the base. Key electrical parameters include a repetitive peak reverse blocking voltage of 600V, an operating junction temperature range from -40°C to 150°C, and a maximum reverse recovery time of 120ns at 150A. Thermal resistance from junction to case is typically 0.137°C/W per diode.

Feature Summary

• Super fast recovery time for high-speed switching applications
• Isolated mounting design compatible with common heatsinks
• Metal baseplate construction for efficient thermal management
• RoHS compliant manufacturing

Applications

• Free wheeling circuits
• Welding machines

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact pinout configuration (QRF vs QRD/QRC) and terminal type. Confirm RoHS compliance status and mounting torque specifications (26 in-lb for M6 screws) during integration. Ensure thermal interface material selection aligns with the specified contact thermal resistance requirements for optimal heat dissipation performance.

Selection Notes

Select this component for applications requiring robust current handling up to 210A with rapid reverse recovery characteristics. The dual diode configuration supports bridge or freewheeling topologies. Evaluate thermal constraints based on the 0.137°C/W junction-to-case resistance and ensure adequate heatsinking to maintain junction temperatures within the -40°C to 150°C operational range under expected load conditions.
