BYG10G-M3/TR3

Overview

The BYG10G-M3/TR3 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor. It features a 1.5 A average forward current rating and a 400 V maximum repetitive reverse voltage. The device utilizes a DO-214AC (SMA) surface-mount package with glass passivation for the junction. Key electrical characteristics include a maximum non-repetitive peak surge current of 30 A, a typical reverse leakage current of 1 µA, and a maximum forward voltage drop of 1.15 V. It operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivated junction provides stable performance and low reverse leakage current.
• Controlled avalanche characteristics ensure reliability under transient voltage conditions.
• Low profile SMA package design facilitates automated placement in high-volume manufacturing.

Applications

• General purpose rectification in power supply circuits.
• Freewheeling diodes in consumer electronics applications.
• Rectification in automotive electronic systems.
• Power conversion stages in telecommunication equipment.

Procurement Notes

Verify the specific suffix configuration against official Vishay documentation to confirm compliance status and qualification grade. Ensure the ordering part number matches the required RoHS directive adherence and AEC-Q101 automotive qualification if applicable. Cross-reference the manufacturer datasheet for any recent product change notices or environmental compliance updates prior to final procurement decisions.

Selection Notes

Select this component for designs requiring robust standard recovery performance in compact surface-mount layouts. The 1.5 A current capacity and 400 V blocking voltage suit general-purpose AC-DC conversion tasks. Consider the thermal management requirements associated with the SMA package footprint and the specified maximum junction temperature limits during circuit simulation.

Part Context

This device belongs to the BYG10 series of silicon planar fast recovery rectifiers designed for surface-mount applications. The series offers a range of voltage ratings from 200 V to 1600 V while maintaining consistent mechanical dimensions. The M3 suffix typically indicates lead-free construction compliant with international environmental standards, distinguishing it from older commercial-grade variants.

Replacement Considerations

Direct substitutes within the same family include BYG10D-M3/TR3 (200 V) and BYG10H-M3/TR3 (600 V), provided voltage ratings align with circuit requirements. Verify that alternative components match the DO-214AC package outline and thermal characteristics to ensure physical compatibility without redesigning the PCB footprint.
