Overview
The AS3PD-M3/87A is a standard recovery rectifier from Vishay, featuring a dual anode configuration in a TO-277A (SMPC) package. It supports a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 4.0 A per diode. The device exhibits a typical forward voltage of 1.1 V at the rated current and a maximum surge current capability of 100 A. Reverse leakage current is specified at 10 µA, with a reverse recovery time of 2.5 µs. Operating junction temperature ranges from -55 °C to +150 °C.
Feature Summary
- Dual anode configuration for common cathode applications
- Avalanche-rated construction for robust transient handling
- Surface mount design in compact TO-277A package
Applications
- General purpose rectification in power supplies
- Freewheeling diodes in DC-DC converters
- Protection circuits requiring avalanche ruggedness
Procurement Notes
Verify the specific suffix /87A corresponds to reel packaging when ordering. Confirm RoHS compliance status via official documentation prior to integration. Ensure thermal management aligns with the specified junction temperature limits during operation.
Selection Notes
Select this component for designs requiring a dual anode topology in a surface mount form factor. The 200 V rating suits low-voltage DC systems. Evaluate thermal dissipation requirements against the 4.0 A continuous current capability and package thermal resistance characteristics.
Part Context
This part belongs to Vishay’s AS3P series of dual anode rectifiers. It utilizes the eSMP trademarked SMPC footprint. The series provides options for various voltage ratings within the same physical envelope to simplify supply chain management for multi-voltage product lines.
Replacement Considerations
Cross-reference with other Vishay AS3P variants for different voltage ratings. Verify pinout compatibility with existing footprints before substituting.
