BYG10DHE3_A/H

Overview

The BYG10DHE3_A/H is a standard avalanche rectifier manufactured by Vishay Semiconductors. It features a single configuration in a DO-214AC (SMA) surface-mount package. Key electrical parameters include a maximum average forward current of 1.5 A and a repetitive peak reverse voltage of 200 V. The device exhibits a maximum forward voltage of 1.15 V, a reverse current of 1 uA, and a recovery time of 4 us. It supports a maximum surge current of 30 A and operates within a junction temperature range of -55 C to +150 C. This component holds AEC-Q101 qualification.

Feature Summary

• Controlled avalanche characteristics for robust performance under transient conditions
• Glass passivated junction ensuring low reverse current stability
• High surge current capability suitable for demanding power applications
• Low profile package design optimized for automated placement processes

Applications

• General purpose rectification in power supplies
• Inverter circuits
• Converter systems
• Freewheeling diodes for consumer electronics
• Automotive electronic modules
• Telecommunication equipment

Procurement Notes

Verify the specific suffix HE3 confirms RoHS compliance and absence of halogens as per Vishay standards. Confirm AEC-Q101 automotive qualification status matches project requirements. Ensure the DO-214AC package dimensions align with PCB footprint specifications. Check for any recent Product Change Notifications that may affect mechanical or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a standard recovery rectifier with avalanche rating is required for space-constrained designs. The SMA package offers a compact solution compared through-hole alternatives. Consider the 1.5 A current rating and 200 V blocking voltage against circuit load profiles. Verify thermal management needs given the 150 C maximum junction temperature limit and ambient operating conditions.

Part Context

This part belongs to the BYG10 series of standard avalanche rectifiers from Vishay. The series covers various voltage ratings while maintaining consistent current handling capabilities. The HE3 suffix denotes environmental compliance, distinguishing it from commercial grade variants. These components are engineered for reliability in both industrial and automotive environments.

Replacement Considerations

Direct substitutes within the same family include BYG10EHE3_A/H and BYG10FHE3_A/H for higher voltage ratings. For lower voltage applications, BYG10BHE3_A/H or BYG10CHE3_A/H may be considered. Ensure replacement parts maintain the DO-214AC package and AEC-Q101 qualification if automotive use is intended.
