ES3A-M3/9AT

Single Diodes Overview

The ES3A-M3/9AT is a single standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 50 V and an average forward rectified current of 3 A. The component utilizes the DO-214AB (SMC) surface-mount package. Key electrical characteristics include a maximum DC reverse leakage current of 10 µA at 50 V, a typical forward voltage of 1.1 V at 3 A, and a maximum non-repetitive peak surge current of 100 A. It operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Glass passivated junction construction for enhanced environmental stability
• High surge current capability designed for transient protection
• Surface-mount SMC package optimized for automated PCB assembly

Single Diodes Applications

• General-purpose rectification in power supply circuits
• Reverse polarity protection in electronic systems
• DC output rectification in consumer electronics

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact packaging and compliance status. Confirm RoHS3 and REACH compliance requirements with the supplier. Ensure the DO-214AB footprint matches the design layout. Check for any recent Product Change Notifications that may affect material composition or manufacturing location before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 3 A current rating and 50 V blocking voltage are required in a compact surface-mount form factor. Compare forward voltage drop specifications against alternative manufacturers to ensure thermal management compatibility. Verify that the surge current rating meets the peak load demands of the target application circuit without exceeding device limits.

Single Diodes Part Context

This part belongs to the ES3 series of glass-passivated fast recovery rectifiers from Vishay. The M3 suffix indicates compliance with current EU Directive 2015/863 regarding restricted substances. The DO-214AB package provides a robust mechanical solution for high-current applications requiring minimal board space compared to through-hole alternatives.

Single Diodes Replacement Considerations

Direct substitutes include the ES3A-E3/9AT variant. Other compatible parts from different manufacturers must match the 3 A current, 50 V voltage, and DO-214AB package dimensions.
