AS1PDHM3/84A

Overview

The AS1PDHM3/84A is a surface-mount Schottky rectifier from Vishay, part of the AS1PD series. It features a DO-220AA (SMP) package with two pins. Key electrical parameters include a maximum repetitive peak reverse voltage (Vrrm) of 200 V and an average forward current (If) of 1.5 A. The device exhibits a typical peak reverse recovery time (trr) of 1.5 μs. Maximum forward voltage (Vf) is 1.15 V at rated current, with a peak reverse leakage current (Ir) of 100 μA. It supports a non-repetitive peak forward surge current (Ifsm) of 30 A and operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Utilizes glass passivated chip junction technology for reliable operation.
• Features controlled avalanche characteristics suitable for harsh environments.
• Designed with a very low profile for automated placement efficiency.

Applications

• Automotive electronics systems requiring AEC-Q101 qualification
• High-frequency rectification in power supply circuits
• DC-DC converter applications

Procurement Notes

Verify the specific ordering suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS directives and WEEE compliance requirements for your region. Confirm that the AEC-Q101 automotive qualification aligns with your system's reliability standards before finalizing procurement.

Selection Notes

Select this component when a 200 V Schottky barrier rectifier with 1.5 A continuous current capability is required in a compact SMP package. Consider its low forward voltage drop for improved efficiency in low-voltage applications. Verify that the 1.5 μs recovery time meets the switching frequency requirements of the target circuit design.

Part Context

This device belongs to Vishay's AS1PD series of high-current density standard avalanche surface mount rectifiers. The series is characterized by its eSMP package format, which offers a typical height of 1.1 mm. These components are engineered for high reliability in automotive and industrial applications, combining robust electrical performance with space-saving surface-mount technology.

Replacement Considerations

Check Vishay datasheets for direct pin-compatible alternatives within the AS1PD family or other Vishay SMP packages with matching voltage and current ratings. Ensure any substitute maintains the same AEC-Q101 qualification if automotive use is intended. Verify thermal and mechanical compatibility before substitution.
