BYG10M

Overview

The BYG10M is a standard avalanche SMD rectifier diode manufactured by Diotec Semiconductor. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 1000 V, with a breakdown threshold exceeding 1050 V. The device supports a peak forward surge current of 27 A at 50 Hz and 30 A at 60 Hz. Electrical characteristics include a maximum forward voltage of 1.15 V at 1.5 A and a leakage current below 5 µA at 25°C. The component operates within a junction temperature range of -50 to +150°C and utilizes the DO-214AC (SMA) surface-mount package.

Feature Summary

• Engineered with controlled avalanche characteristics for non-repetitive peak reverse avalanche energy handling up to 20 mJ.
• Designed for commercial-grade applications requiring high reliability in standard environments.
• Provides polarity protection capabilities alongside general-purpose rectification functions.

Applications

• Input rectification for cable-connected control boxes (ICCB) in electric vehicles
• Power supply circuits
• Polarity protection systems

Procurement Notes

Verify that the specific ordering suffix matches the required electrical parameters, as the BYG10M designation corresponds to the 1000V rating within the BYG10 series. Confirm compliance with RoHS and ELV directives if mandated by your project specifications. Ensure the procurement documentation references the latest datasheet revision to guarantee alignment with current manufacturing standards and thermal resistance values.

Selection Notes

Select this component when a surface-mount solution is required for 50/60Hz mains rectification or power supply applications. The device is suitable where standard recovery times are acceptable but avalanche ruggedness is necessary for transient suppression. Consider the thermal resistance of 100 K/W (junction-to-ambient) for PCB layout planning to ensure operation remains within the specified temperature limits under load.

Part Context

The BYG10M belongs to the BYG10D through BYG10Y family of standard avalanche SMD rectifier diodes produced by Diotec Semiconductor. This series covers various voltage ratings from 400 V to 1600 V, sharing common mechanical dimensions and thermal characteristics. The product is classified as commercial grade, intended for standard industrial and consumer electronics applications rather than specialized automotive or life-support systems.

Replacement Considerations

Cross-reference with other BYG10 series variants such as BYG10K or BYG10J if lower voltage ratings are acceptable. Verify pinout compatibility with the DO-214AC package before substitution. No direct equivalent part numbers are confirmed in the provided source material.
