85EPF04

Overview

The Vishay 85EPF04 is a fast soft recovery QUIETIR rectifier diode rated for 400 V repetitive peak reverse voltage and 85 A average forward current at a case temperature of 75 °C. It features a maximum forward voltage drop of 1.3 V at 85 A and a typical reverse recovery time of 70 ns. The device utilizes glass passivation for stability under severe thermal cycling and is housed in the PowIRtab package with a junction-to-case thermal resistance of 0.35 °C/W.

Feature Summary

• Optimized for combined short reverse recovery time and low forward voltage drop
• Glass passivation ensures stable operation under severe temperature and power cycling conditions
• PowIRtab package provides excellent die-to-footprint ratio and sturdy connectivity for high current environments

Applications

• Output rectification and freewheeling in inverters, choppers, and converters
• Input rectification where severe restrictions on conducted EMI are required

Procurement Notes

Verify that the specific order matches the 85EPF04 part number to ensure the correct 400 V rating. Confirm the package type is PowIRtab and check for any suffixes indicating lead variations. Ensure the application environment aligns with the industrial level qualification standards specified by the manufacturer.

Selection Notes

Select this component when high surge capability and low conduction losses are critical. The 85EPF04 supports an RMS current of 160 A and a non-repetitive surge current of 1100 A. Consider the thermal resistance characteristics and mounting torque requirements when designing the heatsink interface for optimal performance.

Part Context

This component belongs to the 85EPF.. QUIETIR series from Vishay General Semiconductor - Diodes Division. The series includes variants with different voltage ratings ranging from 200 V to 600 V, all sharing the same 85 A current rating and PowIRtab packaging technology designed for robust industrial applications.

Replacement Considerations

Consult the manufacturer's documentation for direct substitutes. Higher voltage options within the same series include the 85EPF06 (600 V). For lower voltage requirements, the 85EPF02 (200 V) is available. Contact the factory for parts exceeding the standard 600 V range up to 1600 V.
