BYG20JHE3_A/I

Overview

The BYG20JHE3_A/I is an ultrafast avalanche rectifier from Vishay General Semiconductor, rated for a maximum repetitive peak reverse voltage of 600 V and an average forward current of 1.5 A. It features a soft recovery characteristic with a maximum reverse recovery time of 75 ns at specified test conditions. The device supports a peak forward surge current of 30 A and operates within a junction temperature range of -55 °C to +150 °C. Packaged in the low-profile SMA (DO-214AC) surface-mount format, it meets AEC-Q101 automotive qualification standards.

Feature Summary

• Ultrafast reverse recovery time with soft recovery characteristics
• Avalanche energy rating for non-repetitive pulse operation
• Glass passivated pellet chip junction for high reliability
• Automotive grade qualification compliant with AEC-Q101

Applications

• High frequency rectification in power supplies
• Inverter and converter circuits
• Freewheeling diodes for consumer electronics
• Freewheeling diodes for automotive systems
• Telecommunication equipment

Procurement Notes

Verify that the specific ordering code matches the required voltage rating and package type. Confirm AEC-Q101 qualification status if automotive application is intended. Ensure compliance with RoHS directives and check material categorization documentation for environmental requirements before finalizing procurement specifications.

Selection Notes

Select this component when a single-diode configuration with 600 V blocking capability is required. The DO-214AC package suits automated placement processes. Consider the avalanche capability for inductive load switching applications. Verify thermal resistance parameters against the specific PCB layout and ambient temperature constraints of the design.

Part Context

This part belongs to the BYG20 series of ultrafast SMD rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as 200 V and 400 V options. The HE3 suffix indicates RoHS compliance combined with AEC-Q101 automotive qualification, distinguishing it from commercial grade equivalents.

Replacement Considerations

Direct substitutes within the same family include BYG20DHE3_A/I and BYG20GHE3_A/I, which share identical packages and electrical characteristics except for their respective maximum repetitive peak reverse voltage ratings of 200 V and 400 V.
