Overview
The AS4PD-M3/87A is a standard avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current rating of 2.4 A. The component utilizes a surface mount TO-277A (SMPC) package, designed for robust performance in compact circuit layouts.
Feature Summary
- Incorporates avalanche rated construction for enhanced ruggedness
- Utilizes plastic encapsulation for environmental protection
- Designed for surface mount assembly processes
Applications
- General purpose rectification in power supplies
- Protection circuits requiring avalanche capability
- Industrial electronic equipment
Procurement Notes
Verify the specific suffix /87A against official Vishay documentation to confirm tape and reel specifications. Ensure the ordering part number matches the required packaging format before procurement. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential product change notices affecting this specific variant.
Selection Notes
Select this component when a 200 V reverse voltage rating and 2.4 A current capacity are required in a surface mount form factor. The TO-277A package offers a balance of thermal performance and board space efficiency. Consider the avalanche rating if the application involves transient energy absorption or specific switching conditions.
Part Context
This device belongs to Vishay's general-purpose diode portfolio, specifically utilizing the SMPC package style. It serves as a surface mount alternative to through-hole equivalents, maintaining similar electrical characteristics while enabling automated assembly. The avalanche rating distinguishes it from standard non-avalanche variants within the same voltage and current class.
Replacement Considerations
Check for AS4PD-M3/86A as a potential variant with different packaging. Verify pinout compatibility and thermal resistance values when substituting with other 200 V 2.4 A SMPC diodes from Vishay or other manufacturers.
