BYG20GHE3_A/H

Overview

The BYG20GHE3_A/H is a single fast recovery avalanche rectifier manufactured by Vishay General Semiconductor. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 400 V. The device utilizes a glass-passivated junction within a DO-214AC (SMA) surface-mount package. Key electrical characteristics include a typical reverse recovery time of 75 ns, a maximum forward voltage of 1.4 V at 1.5 A, and a low reverse leakage current of 1 µA at 400 V. It supports an operating junction temperature range from -55°C to +150°C and holds AEC-Q101 qualification for automotive reliability.

Feature Summary

• Incorporates avalanche capability for enhanced robustness against transient voltage events.
• Features a cavity-free glass-passivated junction structure designed for high reliability applications.
• Provides fast recovery performance with minimal reverse recovery charge for efficient switching.
• Meets AEC-Q101 standards to ensure suitability for demanding automotive electronic environments.

Applications

• Automotive power supply circuits requiring qualified components.
• High-frequency switching power supplies and converters.
• Free-wheeling diode applications in inductive load protection.
• General-purpose rectification in industrial electronics.

Procurement Notes

Verify the specific suffix configuration when ordering, as variations such as TR3 or A/H may denote different packaging formats like tape-and-reel or cut-tape. Confirm that the procurement specification explicitly requires AEC-Q101 qualification if the application demands automotive-grade reliability. Ensure the selected part number matches the required reverse voltage and current ratings for the target circuit design.

Selection Notes

Select this component for designs requiring a surface-mount fast recovery diode with avalanche ruggedness. The DO-214AC package offers a compact footprint suitable for space-constrained PCB layouts. Consider the 75 ns reverse recovery time for high-frequency operation where standard rectifiers would exhibit excessive losses. Verify thermal management requirements given the 150°C maximum junction temperature limit.

Part Context

This device belongs to the BYG20 series of fast recovery rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as BYG20D through BYG20J. The 'E3' designation indicates compliance with RoHS directives using matte tin terminations. The 'A/H' suffix typically denotes specific packaging or reel configurations provided by the manufacturer.

Replacement Considerations

Direct substitutes within the same family include BYG20G-E3/TR3, which shares identical electrical specifications but may differ in packaging format. Other Vishay parts in the BYG20 series offer similar performance with varying voltage ratings. Cross-brand replacements must match the 1.5 A current, 400 V voltage, and SMA package constraints.
