BYG10D-M3/TR3

Overview

The BYG10D-M3/TR3 is a standard avalanche SMD rectifier from Vishay General Semiconductor, housed in a DO-214AC (SMA) package. It features a maximum repetitive peak reverse voltage of 200 V and an average forward current rating of 1.5 A. The device supports a peak forward surge current of 30 A and exhibits a maximum instantaneous forward voltage of 1.15 V at 1.5 A. Electrical characteristics include a maximum DC reverse current of 1 μA at 25 °C and a maximum reverse recovery time of 4 μs. The component operates within a junction temperature range of -55 to +150 °C.

Feature Summary

• Controlled avalanche characteristics for robust performance under inductive load switching
• Glass passivated junction ensuring low reverse current stability
• High surge current capability suitable for demanding power applications
• Low profile package optimized for automated surface-mount placement

Applications

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

Procurement Notes

Verify the specific ordering suffix to confirm compliance requirements. The M3 suffix indicates a halogen-free, RoHS-compliant commercial grade product. Confirm that the TR3 designation corresponds to the 13-inch diameter plastic tape and reel packaging format with a base quantity of 7500 units. Ensure the procurement matches the exact part number to guarantee the correct electrical ratings and qualification status.

Selection Notes

Select this component when a 200 V blocking voltage and 1.5 A continuous current are required in a compact SMA footprint. The controlled avalanche feature makes it suitable for applications involving inductive loads where energy dissipation during switch-off occurs. Verify thermal management requirements against the specified junction-to-lead and junction-to-ambient thermal resistance values for the intended mounting configuration.

Part Context

This device belongs to the BYG10 series of standard avalanche SMD rectifiers manufactured by Vishay General Semiconductor. The series includes variations with different voltage ratings ranging from 200 V to 1600 V, all sharing the same DO-214AC package and core electrical architecture. The M3 variant specifically denotes halogen-free construction compliant with JEDEC JS709A standards.

Replacement Considerations

Compatible substitutes within the same family include BYG10D-E3/TR3 and BYG10DHM3/TR. These parts share identical electrical specifications and mechanical dimensions. The HM3 suffix indicates AEC-Q101 automotive qualification, which may be preferred for automotive applications requiring enhanced reliability standards compared to the commercial grade M3 version.
