Overview
The AU1PD-M3/85A is a single ultrafast recovery rectifier manufactured by Vishay Semiconductors. It features a 200 V reverse voltage rating and supports a continuous forward current of 1 A. The device exhibits a maximum forward voltage of 1.5 V and a low reverse leakage current of 1 uA. Its ultrafast recovery time is specified at 75 ns, with a peak forward surge current capability of 30 A. Operating within a temperature range of -55 °C to +175 °C, it utilizes the eSMP package (DO-220AA) for surface mount applications.
Feature Summary
- Ultrafast recovery characteristics enable efficient switching performance in high-frequency circuits.
- Avalanche rated construction provides robustness against transient voltage events.
- Low thermal resistance design facilitates effective heat dissipation in compact form factors.
Applications
- High-frequency power supply rectification
- Free-wheeling diodes in DC-DC converters
- Snubber circuits in switching mode power supplies
Procurement Notes
Verify the specific suffix /85A corresponds to the required tape and reel quantity when ordering. Confirm RoHS compliance status through official datasheets prior to integration. Ensure the DO-220AA footprint matches the target PCB layout. Cross-reference the manufacturer part number directly with Vishay documentation to avoid substitution errors.
Selection Notes
Select this component for designs requiring fast recovery times under 100 ns with moderate current handling. The 200 V rating suits low-voltage DC bus applications. Consider the 1.5 V forward drop for efficiency calculations. The wide operating temperature range supports demanding industrial environments without derating adjustments.
Part Context
This rectifier belongs to the AU1P series from Vishay, designed for general-purpose ultrafast recovery applications. The eSMP packaging offers space-saving advantages over traditional axial leads. It complements Vishay's broader portfolio of discrete semiconductors aimed at improving power conversion efficiency in modern electronic systems.
Replacement Considerations
Consult Vishay technical support for verified cross-references. Ensure any substitute maintains identical pinout, voltage ratings, and recovery speed specifications.
