AS4PDHM3/86A

Overview

The AS4PDHM3/86A is a standard recovery rectifier from Vishay Semiconductors, housed in the SMPC (TO-277A-3) surface-mount package. It features a single cathode dual anode configuration with a 1 kV repetitive peak reverse voltage and a 4 A average forward current rating. The device exhibits a maximum forward voltage of 1.044 V at rated current and a typical reverse leakage current of 350 nA. It supports a surge current of 100 A and operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Utilizes oxide planar chip junction technology for robust performance
• Designed for automated placement with a low-profile surface-mount form factor
• Compliant with RoHS directives and halogen-free standards

Applications

• General purpose rectification in power supply circuits
• Freewheeling diode applications in inductive load switching
• DC-AC conversion stages requiring high voltage isolation

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact packaging and tape-and-reel specifications. Ensure the ordering code matches the required SMPC package variant. Confirm compliance status with current environmental regulations before finalizing procurement orders.

Selection Notes

Select this component when a high-voltage standard recovery rectifier is required in a compact surface-mount footprint. The dual anode configuration allows for flexible circuit topologies. Verify that the thermal management design accommodates the specified operating temperature range and forward voltage drop characteristics.
