ES3AHE3/9AT

Single Diodes Overview

The ES3AHE3/9AT is a standard rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 50 V and an average forward rectified current (Io) of 3 A. The device utilizes a glass-passivated junction for environmental protection and is housed in the DO-214AB (SMC) surface-mount package. Key electrical parameters include a maximum reverse leakage current of 10 µA at 50 V, a typical forward voltage of 1.1 V at 3 A, and a fast recovery time of less than 20 ns. The component operates within a junction temperature range of -55°C to 150°C.

Single Diodes Feature Summary

• Glass-passivated junction construction provides enhanced environmental protection and reliability.
• Fast recovery characteristics with a reverse recovery time of less than 20 ns.
• High surge overload capability suitable for demanding power applications.

Single Diodes Applications

• General-purpose rectification in AC-to-DC conversion circuits
• Freewheeling diodes in inductive load switching applications
• Polarity protection in DC power supply inputs

Single Diodes Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, as variations exist between tape-and-reel and cut-tape formats. Ensure compliance with RoHS3 directives and check for AEC-Q101 automotive qualification status if required for the target application. Confirm the manufacturer part number matches the exact voltage and current ratings specified in the design requirements before procurement.

Single Diodes Selection Notes

Select this component when a 50 V reverse voltage rating and 3 A continuous current capacity are required in a compact SMC package. The fast recovery time makes it suitable for higher frequency rectification compared to standard slow recovery diodes. Consider the operating temperature range and thermal management needs for the specific enclosure environment.

Single Diodes Part Context

This component belongs to the ES3x series of high-current, fast-recovery rectifiers from Vishay. The series offers various voltage ratings to suit different circuit requirements while maintaining a consistent DO-214AB footprint. The HE3 suffix indicates a Halogen-free and RoHS-compliant variant within the product line.

Single Diodes Replacement Considerations

Direct substitutes may include other 50 V, 3 A fast recovery diodes in the DO-214AB package from manufacturers such as STMicroelectronics or Onsemi. Verify that replacement parts match the reverse recovery time and forward voltage specifications to ensure circuit compatibility.
