QRD3310007

Overview

The Powerex QRD3310007 is a fast recovery diode module rated for 3300 Volts and 100 Amperes. It features a maximum repetitive peak reverse blocking voltage of 3300 V and a typical on-state voltage of 3.3 V at 100 A. The device exhibits a maximum reverse recovery time of 1.2 µs and a thermal resistance from junction to case of 0.12 °C/W per diode. Electrical isolation between the circuit and baseplate is rated at 6000 V RMS.

Feature Summary

Fast switching capability with a maximum reverse recovery time of 1.2 µs
High-voltage electrical isolation of 6000 V RMS between terminals and baseplate
Low thermal impedance utilizing DBC AlN isolation material and a copper baseplate

Applications

Switching power supplies
Inverters
Choppers
Welding power supplies
Free wheeling diode circuits
High frequency rectifiers

Procurement Notes

Verify the specific datasheet revision, as the provided documentation is marked Preliminary Rev. 4 dated 02/16. Confirm that the manufacturer's testing data aligns with your design requirements, noting their disclaimer regarding suitability and reliability claims. Ensure mounting torque specifications are strictly followed during installation.

Selection Notes

Select this module for high-frequency applications requiring robust voltage handling up to 3300 V. Consider the 1.2 µs reverse recovery time for efficiency in hard-switching topologies. Evaluate the thermal management strategy based on the 0.12 °C/W junction-to-case resistance and the requirement for a common heatsink compatible with the isolated copper baseplate.

Part Context

This component belongs to the Powerex Fast Recovery Diode Module series designed for demanding industrial environments. The product line emphasizes fast switching performance and ease of integration into larger power systems through its isolated mounting structure. It serves as a critical semiconductor solution for managing high currents and voltages in modern power electronics.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 3300 V rating, 100 A current capacity, and physical dimensions for proper mechanical fit.
