Overview
The AS4PDHM3_A/H is a standard recovery rectifier from Vishay Semiconductors, designed for surface-mount applications. It features a single configuration with a 200 V reverse voltage rating and a 4 A average forward current capability. The device utilizes the SMPC (TO-277A-3) package and exhibits a typical forward voltage of 920 mV at rated current. Key electrical parameters include a maximum surge current of 100 A, a reverse leakage current of 350 nA, and a reverse recovery time of 1.8 µs. It operates within a temperature range of -55 °C to +175 °C and holds AEC-Q101 qualification.
Feature Summary
- Glass passivated chip junction for enhanced reliability
- Controlled avalanche characteristics for rugged operation
- Low leakage current performance
- High forward surge current capability
Applications
- Automotive electronics systems requiring AEC-Q101 qualified components
- General purpose rectification in surface-mount circuits
- Freewheeling diode applications in power supplies
Procurement Notes
Verify the specific suffix _A/H against the manufacturer's datasheet to confirm pinout and packaging details. Ensure the ordering quantity aligns with the reel packaging requirements specified by Vishay. Cross-reference the AEC-Q101 qualification status if automotive compliance is mandatory for the design. Confirm RoHS and halogen-free status through official documentation before integration.
Selection Notes
Select this component when a standard recovery rectifier with high current density in a low-profile surface-mount package is required. The 200 V rating suits low-voltage DC-DC converters and freewheeling applications. Consider the 1.8 µs reverse recovery time for general frequency operations rather than high-speed switching. The TO-277A footprint offers a compact solution for automated placement processes.
Part Context
This part belongs to the AS4P series of high current density standard avalanche surface mount rectifiers. The eSMP series designation indicates a specialized surface-mount package optimized for automated assembly. The product line emphasizes low profile and high reliability for demanding electronic environments.
Replacement Considerations
Consult Vishay's official substitution guide for verified alternatives. Generic equivalents may not match the controlled avalanche characteristics or AEC-Q101 qualification. Verify package compatibility and thermal performance before substituting.
