Overview
The AS1PDHM3/85A 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 a maximum average forward rectified current (If) of 1.5 A. The device exhibits a typical reverse recovery time (trr) of 1.5 µs and a maximum forward voltage drop (Vf) of 1.15 V. Reverse leakage current is specified at 100 µA. It supports a peak non-repetitive forward surge current (Ifsm) of 30 A and operates within a temperature range of -55°C to 175°C.
Feature Summary
- Schottky barrier technology for low forward voltage drop
- Glass passivated chip junction for reliability
- Controlled avalanche characteristics
Applications
- High frequency rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging variations. Ensure the component meets required automotive or industrial standards if applicable. Confirm lead times and availability directly with authorized distributors as stock levels fluctuate. Validate RoHS compliance status for your specific region's regulatory requirements before finalizing procurement.
Selection Notes
Select this component when a low-profile surface-mount Schottky rectifier is needed for high-frequency applications. The 200 V rating and 1.5 A current capacity suit compact power designs. Consider the 1.5 µs reverse recovery time for switching speed requirements. The DO-220AA package facilitates automated placement. Verify thermal management needs given the 175°C maximum junction temperature capability.
Part Context
This device belongs to Vishay's AS1PD series of high-current density standard avalanche surface mount rectifiers. The series utilizes glass passivated chip junction technology to ensure robust performance. Components in this family are designed for automated assembly processes due to their small form factor. The AS1PDHM3/85A specifically integrates Schottky characteristics within this standardized surface-mount architecture.
Replacement Considerations
Check for direct equivalents within the AS1PD series with different voltage ratings if system requirements change. Verify pinout compatibility with existing PCB layouts. Ensure replacement components maintain similar thermal resistance and package dimensions for mechanical fit.
