AS1PD-M3/85A

Overview

The AS1PD-M3/85A is a Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a 200 V repetitive peak reverse voltage and a 1.5 A average forward current rating. The device utilizes the eSMP (DO-220AA) surface-mount package for compact circuit integration. Key electrical characteristics include a maximum forward voltage of 1.15 V and a peak non-repetitive forward surge current capability of 30 A. The component is designed for high-efficiency power conversion applications requiring low forward drop and fast switching performance.

Feature Summary

• Schottky barrier construction provides ultra-low forward voltage drop for improved energy efficiency
• High thermal stability supports operation at junction temperatures up to 175°C
• eSMP surface-mount package enables automated assembly and reduced board space consumption

Applications

• DC-DC converter output rectification
• Free-wheeling diodes in synchronous rectifier circuits
• Power supply input protection stages

Procurement Notes

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with design requirements. Confirm RoHS compliance status and REACH SVHC declarations prior to procurement. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package damage during soldering processes.

Selection Notes

Select this component when low forward voltage drop is critical for system efficiency. The 200 V rating suits medium-voltage DC bus applications. Verify that the 1.5 A continuous current rating meets the load requirements under worst-case thermal conditions. Consider the DO-220AA footprint constraints during PCB layout planning.

Part Context

This part belongs to the AS1PD series of Schottky rectifiers from Vishay. The series is characterized by its use of silicon nitride passivation for enhanced reliability. The eSMP package variant offers a compact form factor suitable for modern high-density electronic assemblies requiring robust surface-mount solutions.

Replacement Considerations

Cross-reference with other Vishay AS1PD variants or equivalent Schottky rectifiers in the DO-220AA package. Ensure substitute components match the 200 V reverse voltage, 1.5 A current rating, and 1.5 μs reverse recovery time specifications.
