BYG10D-M3/TR

Overview

The BYG10D-M3/TR 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 operates within a junction temperature range of -55 to +150 °C. Electrical characteristics 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.

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 designed for ideal automated 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 suffix configuration against project requirements. The M3 suffix indicates halogen-free and RoHS-compliant commercial grade material. Confirm the delivery mode matches the intended manufacturing process; TR denotes a 7-inch tape and reel with a base quantity of 1800 units, while TR3 indicates a 13-inch reel with 7500 units. Ensure compatibility with JESD 201 whisker test standards during component qualification.

Selection Notes

Select this component when a 200 V blocking voltage and 1.5 A continuous current are required in a surface-mount SMA footprint. The controlled avalanche rating makes it suitable for environments with significant inductive kickback. Verify that the thermal resistance parameters align with the PCB copper area and ambient temperature conditions to maintain the junction temperature within the specified 150 °C limit.

Part Context

This part belongs to the BYG10 series of standard avalanche rectifiers, which includes variants with reverse voltages ranging from 200 V to 1600 V. All members share the same DO-214AC case outline and mechanical data. The M3 designation specifically identifies the halogen-free, RoHS-compliant commercial grade version, distinct from the HM3 automotive qualified variant.

Replacement Considerations

Direct substitutes within the same family include BYG10G, BYG10J, BYG10K, BYG10M, and BYG10Y, provided their respective reverse voltage ratings meet or exceed the circuit requirements. Cross-brand replacements must match the DO-214AC package dimensions, 1.5 A current rating, and 200 V minimum blocking voltage.
