Overview
The Powerex QRC3310001 is a fast recovery diode module rated for 3300 V repetitive peak reverse blocking voltage and up to 100 A average forward current. It features an aluminum nitride ceramic substrate for low thermal impedance and a copper baseplate. The module provides 6000 Vrms isolation between the circuit and the baseplate. Key electrical characteristics include a maximum reverse recovery time of 1.2 µs and a typical on-state voltage of 3.3 V at 100 A.
Feature Summary
- Aluminum Nitride (AlN) ceramic substrate for low thermal impedance
- Copper baseplate construction
- High voltage insulation with enhanced creepage and strike clearance distances
- No additional insulation components required
Applications
- Medium voltage drives
- Auxiliary traction applications
- High voltage power supplies
- Motor drives
- Front end rectifiers in 10.2 kV isolation systems
Procurement Notes
Verify the specific datasheet revision, as the provided document is marked preliminary. Confirm that the mounting torque specifications for the #10-32 screws are strictly adhered to during installation to prevent mechanical failure. Ensure the operating junction temperature remains within the specified -40 to 150 °C range for reliable performance.
Selection Notes
Select this module when high voltage isolation and fast recovery times are critical. The 6000 Vrms isolation rating allows for direct mounting on common heatsinks without extra insulators. Consider the thermal resistance values for heat sink design to maintain junction temperatures within limits under varying conduction angles.
Part Context
This component belongs to the QRC series of fast recovery diode modules from Powerex. These modules are designed for demanding industrial applications requiring robust high-voltage handling and efficient thermal management through their isolated packaging structure.
Replacement Considerations
Public confirmed substitute part numbers are not available in the source material.
FAQ
What is the maximum reverse recovery time for the QRC3310001?
The maximum reverse recovery time is 1.2 µs when tested at IF = 100A and di/dt = -200A/µs.
Does the module require additional insulation components for mounting?
No, the module does not require additional insulation components due to its high voltage housing and 6000 Vrms isolation rating.
What is the typical on-state voltage drop at rated current?
The typical on-state voltage (VFM) is 3.3 Volts when the forward current (IF) is 100 Amperes.
