QRF1230R30

Overview

The Powerex QRF1230R30 is a super fast recovery dual diode module rated for 1200 V repetitive peak reverse blocking voltage and 210 A DC current at 80°C case temperature. It features an isolated metal baseplate with 2500 V isolation voltage, enabling easy mounting on common heatsinks. The device exhibits a typical reverse recovery time of 110 ns and low thermal impedance of 0.10 °C/W per diode junction to case.

Feature Summary

• Super fast recovery time for high-speed switching applications
• Isolated metal baseplate design for simplified thermal management
• RoHS compliant construction

Applications

• Free wheeling circuits
• Welding machines
• Plasma cutting machines

Procurement Notes

Verify the specific datasheet revision against the manufacturer's official documentation before finalizing specifications. Confirm that the thermal interface material application meets the contact thermal resistance requirements for your heat sink setup. Ensure mounting torque does not exceed the maximum specified limit to prevent mechanical damage to the module.

Selection Notes

Select this component when high surge current capability and fast recovery characteristics are required in industrial power conversion systems. The dual diode configuration allows for efficient bridge or freewheeling topologies within a single isolated package. Consider the 2500 V isolation rating for safety compliance in high-voltage environments.

Part Context

This module belongs to Powerex's Super Fast Recovery Dual Diode series, designed for robust performance in demanding power electronics. The QRF variant specifically denotes the pinout configuration within the family, sharing core electrical ratings with QRD, QRJ, and QRC models while maintaining distinct terminal arrangements for circuit integration.

Replacement Considerations

Direct replacements include other Powerex modules from the same series such as QRD1230R30, QRJ1230R30, and QRC1230R30, provided the pinout compatibility matches the existing PCB layout. Verify that any substitute maintains the same 1200 V and 210 A ratings along with equivalent thermal characteristics.

FAQ

What is the maximum non-repetitive peak reverse blocking voltage?

The maximum non-repetitive peak reverse blocking voltage (VRSM) is 1300 V, which is defined as VRRM plus 100 V.

How is the module electrically isolated?

The module provides 2500 V RMS isolation between the circuit terminals and the baseplate when all terminals are shorted, measured at 60 Hz for 60 seconds.

What is the typical reverse recovery charge?

The typical reverse recovery charge (Qrr) is 13.8 µC, measured at IF = 210 A and di/dt = -600 A/µs.
