ESH1PDHM3/84A

Single Diodes Overview

The Vishay ESH1PDHM3/84A is a surface-mount Schottky rectifier in the AS1PD series, housed in a DO-220AA package. It features a peak repetitive reverse voltage of 200 V and a maximum average forward current of 1.5 A. The device exhibits a typical reverse recovery time of 1.5 μs and a low forward voltage drop of 1.15 V at rated current. With a peak non-repetitive forward surge current capability of 30 A and a maximum operating junction temperature of 175 °C, it supports high-frequency applications. The component is AEC-Q101 qualified for automotive reliability.

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel configuration. Ensure the component meets RoHS directives and halogen-free requirements for your assembly process. Cross-reference the manufacturer datasheet for thermal derating curves and soldering profiles to guarantee long-term reliability under operational stress conditions.

Single Diodes Selection Notes

Select this component when a Schottky barrier offers superior efficiency over standard silicon rectifiers in low-voltage, high-current scenarios. The 200 V rating provides sufficient headroom for 12 V or 24 V automotive systems. Consider the DO-220AA footprint compatibility with existing PCB layouts and automated placement equipment constraints during the design phase.

Single Diodes Part Context

This part belongs to Vishay's AS1PD series of surface-mount Schottky rectifiers. The series is designed for compact designs requiring high current density and fast switching speeds. The HM3 suffix indicates lead-free termination plating compliant with international environmental standards, distinguishing it from older tin-lead variants.

Single Diodes Replacement Considerations

Direct replacements include other Vishay AS1PD series parts with matching voltage and current ratings, such as the AS1PDHM3/84B for different voltage options. Verify pinout compatibility and thermal resistance characteristics before substituting with components from other manufacturers.
