Procurement Notes

Verify the specific suffix 'QRC' against official datasheets to confirm pinout configuration, as this family includes variants like QRD and QRF with different terminal arrangements. Confirm RoHS compliance status and thermal interface requirements for your specific mounting torque specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed switching performance and robust current handling are required in industrial environments. Ensure the application maintains case temperatures within specified limits to sustain the 210A rating. Verify that the 1200V blocking voltage provides adequate margin for transient voltages in the target circuit topology.

Part Context

This module belongs to Powerex's Super Fast Recovery Dual Diode Module series, designed for demanding power conversion tasks. The QR_1230R30 designation indicates a 1200V, 210A rating within this lineup. These modules utilize advanced semiconductor technology to minimize switching losses while maintaining high reliability in harsh operating conditions.

Replacement Considerations

Direct substitutes within the same package and electrical specification should be sourced from Powerex's QR_1230R30 family documentation. Verify pin compatibility carefully, as QRD, QRC, and QRF variants differ in terminal layout despite sharing core ratings.
