BYG22AHE3_A/I

Overview

The BYG22AHE3_A/I is a fast recovery rectifier manufactured by Vishay Semiconductors. It features a single diode configuration housed in the DO-214AC (SMA) surface-mount package. The device supports a maximum average forward rectified current of 2.0 A and a repetitive peak reverse voltage of 50 V. Key electrical characteristics include a maximum reverse leakage current of 1 µA, a typical forward voltage drop of 1.1 V at rated current, and a maximum non-repetitive surge current capability of 35 A. The unit exhibits a fast reverse recovery time of 25 ns. It is qualified to AEC-Q101 standards for automotive applications and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Fast recovery performance with a 25 ns reverse recovery time suitable for high-frequency switching applications.
• Automotive-grade reliability certified under the AEC-Q101 standard for enhanced durability.
• Surface-mount construction in a compact DO-214AC package designed for automated placement.

Applications

• High-frequency power supply circuits
• Automotive electronics systems
• DC-DC converter stages

Procurement Notes

Verify that the ordering suffix matches the required package variant, as the 'I' suffix typically denotes specific tape-and-reel packaging distinct from other variants like 'H'. Confirm the component meets AEC-Q101 requirements if used in automotive designs. Ensure the selected part number aligns with the specific voltage and current ratings needed for the target application circuit.

Selection Notes

Select this component when a 50 V rating and 2 A continuous current capacity are required in a small surface-mount footprint. The fast recovery characteristic makes it appropriate for applications demanding low switching losses. Consider the thermal management capabilities of the DO-214AC package relative to the expected power dissipation in the final design.

Part Context

This component belongs to the BYG series of SuperEctifier fast recovery rectifiers from Vishay. These devices utilize advanced silicon planar technology to provide robust performance in surface-mount formats. The series is engineered to replace bulkier axial-leaded components while maintaining high reliability and fast switching speeds for modern electronic designs.

Replacement Considerations

Direct substitutes may include the BYG22AHE3_A/H or BYG22AHE3_A/G, provided the packaging differences are acceptable for the assembly process. Verify pinout compatibility and ensure that any alternative maintains the same 50 V reverse voltage and 2 A forward current ratings.
