BYG10MHM3_A/I

Overview

The BYG10MHM3_A/I is a standard avalanche SMD rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and operates in the SMA (DO-214AC) package. The device supports an average forward current of 1.5 A and a maximum repetitive peak reverse voltage of 1000 V. Key electrical parameters include a maximum instantaneous forward voltage of 1.15 V at 1.5 A, a maximum DC reverse current of 1 μA at 25 °C, and a maximum reverse recovery time of 4 μs. It withstands a peak forward surge current of 30 A and handles up to 20 mJ of pulse energy in avalanche mode. The component is qualified under AEC-Q101 standards for automotive applications.

Feature Summary

• Controlled avalanche characteristics enable reliable operation during inductive load switching events.
• Glass passivated pellet chip junction provides stable performance with low reverse leakage current.
• Low profile SMA package design is optimized for automated surface-mount placement processes.

Applications

• Freewheeling diodes for consumer electronics
• General purpose rectification in power supplies
• Inverter and converter circuits
• Automotive electronic systems

Procurement Notes

Verify that the ordering code includes the HM3 suffix to confirm halogen-free compliance and RoHS adherence. Ensure the _A/I designation matches the required 7500-unit reel quantity. Confirm AEC-Q101 qualification status if the application requires automotive-grade reliability standards before finalizing procurement specifications.

Selection Notes

Select this component when a high-voltage standard recovery rectifier with avalanche capability is required in a compact surface-mount form factor. The 1000 V rating suits general-purpose power conversion tasks. Verify thermal resistance requirements against the specific PCB copper area and ambient temperature conditions to ensure the junction temperature remains within the specified operating range.

Part Context

This part belongs to the BYG10 series of standard avalanche rectifiers from Vishay. The series includes variants with different reverse voltage ratings ranging from 200 V to 1600 V. All members share the same DO-214AC package and 1.5 A current handling capabilities. The HM3 variant specifically denotes halogen-free construction while maintaining RoHS compliance.

Replacement Considerations

Direct substitutes within the same family include BYG10KHM3_A/I (800 V) and BYG10YHM3_A/I (1600 V). Cross-brand replacements must match the 1.5 A current rating, 1000 V reverse voltage, and SMA package dimensions. Verify reverse recovery time and avalanche energy ratings to ensure functional equivalence in the target circuit.
