Overview
The AS4PMHM3/87A is a single standard recovery rectifier from Vishay, housed in an SMPC (TO-277A-3) package. It features a 1 kV reverse voltage rating and supports a continuous forward current of 4 A. The device exhibits a maximum forward voltage of 920 mV at rated current and handles a peak surge current of 100 A. With a reverse leakage current of 350 nA and a recovery time of 1.8 µs, it operates within a junction temperature range of -55°C to +175°C. This component is qualified under the AEC-Q101 standard for automotive applications.
Feature Summary
- Single diode configuration with avalanche capability
- High thermal stability supporting extended operating temperatures
- Automotive-grade qualification ensuring reliability
Applications
- Automotive power supply circuits
- General-purpose rectification in industrial electronics
- DC-AC conversion stages
Procurement Notes
Verify the specific suffix /87A against official datasheets to confirm reel packaging specifications. Ensure the part number matches the exact electrical ratings required for your design. Cross-reference the manufacturer's latest documentation to confirm availability status and any potential lifecycle changes before finalizing procurement plans.
Selection Notes
Select this component when a robust single-diode solution with high voltage blocking capability is needed. The TO-277A package offers efficient surface-mount integration. Consider the 1.8 µs recovery time for general-purpose applications rather than high-frequency switching. Verify that the 4 A current rating aligns with the circuit's load requirements.
Part Context
This rectifier belongs to Vishay's AS4P series, designed for high-reliability environments. The SMPC package provides a compact footprint suitable for dense PCB layouts. As an AEC-Q101 qualified device, it meets stringent automotive industry standards for durability and performance consistency under varying thermal conditions.
Replacement Considerations
Consult official substitution guides for equivalent parts. Verify pinout compatibility and ensure replacement components meet or exceed the 1 kV voltage and 4 A current ratings.
