ES3F-E3/9AT

Single Diodes Overview

The ES3F-E3/9AT is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 300 V and an average forward rectified current (Io) of 3 A. The device utilizes the DO-214AB (SMC) surface mount package. Key electrical parameters include a maximum forward voltage (Vf) of 1.1 V at 3 A, a reverse leakage current of 10 µA at 300 V, and a junction capacitance of 30 pF at 4 V and 1 MHz. The reverse recovery time (trr) is specified as 50 ns. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Surface mount construction in the DO-214AB (SMC) package for automated assembly
• Standard rectification technology with fast recovery characteristics under 500 ns
• High thermal stability supporting junction temperatures up to 150°C
• Lead-free finish compliant with RoHS 3 directives

Single Diodes Applications

• General purpose rectification in power supply circuits
• Freewheeling diodes in inductive load switching applications
• DC-DC converter output rectification stages

Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm packaging type and compliance status. Ensure the procurement channel provides valid traceability documentation for the Vishay manufacturing lot. Confirm that the received components match the ES3F-E3/9AT designation without unauthorized modifications or counterfeit indicators prior to integration into production lines.

Single Diodes Selection Notes

Select this component when a 3 A current rating and 300 V blocking capability are required in a compact SMC footprint. Consider the 50 ns reverse recovery time for applications requiring faster switching than standard soft recovery diodes but where Schottky voltage limits are insufficient. Evaluate thermal management requirements based on the 1.1 V forward voltage drop at full load conditions.

Single Diodes Part Context

This part belongs to the ES3F series of glass passivated junction rectifiers designed for surface mount applications. The series offers high surge overload capability and robust performance in general-purpose rectification tasks. The E3 suffix indicates lead-free termination material and RoHS compliance, aligning with modern environmental standards for electronic components distributed globally.
