Overview
The AS4PM-M3/86A is a standard recovery rectifier from Vishay Semiconductors, housed in the TO-277A-3 surface-mount package. It features a single cathode dual anode configuration with a maximum repetitive reverse voltage of 1 kV and an average forward current rating of 4 A. The device exhibits a typical forward voltage of 1.044 V and a maximum surge current capacity of 100 A. Reverse leakage current is specified at 350 nA, with a recovery time of 1.8 µs. Operating temperatures range from -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 WEEE regulations
Applications
- General-purpose rectification in power supply circuits
- High-frequency switching applications requiring standard recovery characteristics
- Automotive electronics systems meeting specific reliability standards
Procurement Notes
Verify the complete part number including the /86A suffix to ensure correct reel packaging specifications. Confirm that the required voltage and current ratings align with the circuit design parameters before ordering. Check for any specific automotive qualification requirements if the application demands AEC-Q101 compliance, as this may vary by variant.
Selection Notes
Select this component when a high-voltage standard recovery diode is needed in a compact SMD package. The 1 kV rating suits mains-connected or high-side rectification tasks. Consider the 1.8 µs recovery time for frequency limitations. Ensure thermal management supports the 175°C junction temperature capability in the final assembly environment.
Part Context
This device belongs to the AS4P series of rectifiers manufactured by Vishay Semiconductors. The series utilizes the eSMP (eSMP®) package technology, which provides a small outline footprint suitable for dense PCB layouts. The M3 suffix indicates lead-free termination plating compliant with international environmental standards.
Replacement Considerations
Consult official Vishay documentation for direct cross-reference data. Verify pinout compatibility and electrical parameter margins against potential substitutes. Ensure replacement components meet the same thermal and mechanical specifications for the TO-277A-3 package.
