Overview
The Vishay 80EPF12 is a high-voltage fast soft recovery QUIETIR rectifier diode rated for 1200 V repetitive peak reverse voltage. It provides an average forward current of 80 A and withstands a non-repetitive surge current of 1100 A. The device features a maximum forward voltage drop of 1.35 V at 80 A and a reverse recovery time of 480 ns. Housed in a TO-247AC package, it operates within a junction temperature range of -40 to 150 °C.
Feature Summary
- Fast soft recovery characteristics optimized for combined short reverse recovery time and low forward voltage drop
- Glass passivation ensures stable and reliable operation under severe temperature and power cycling conditions
- Designed for applications requiring strict restrictions on conducted electromagnetic interference
Applications
- Output rectification and freewheeling in inverters, choppers, and converters
- Input rectification where severe restrictions on conducted EMI are required
Procurement Notes
Verify the specific suffix code against official documentation to confirm exact electrical tolerances and packaging specifications. Confirm that the component meets industrial level qualification standards as defined by the manufacturer. Ensure thermal interface materials and mounting torque align with the specified mechanical requirements for optimal heat dissipation.
Selection Notes
Select this component when high voltage blocking capability and controlled soft recovery are necessary to minimize switching losses and electromagnetic noise. Evaluate the thermal resistance parameters to ensure adequate heatsinking for the intended duty cycle. Consider the forward voltage drop characteristics relative to the expected operating current to manage conduction losses effectively.
