BYG24DHE3_A/H

Overview

The BYG24DHE3_A/H is a fast avalanche SMD rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and operates in the SMA (DO-214AC) package. The device supports a maximum repetitive peak reverse voltage of 200 V, an average forward current of 1.5 A at 65 °C, and a peak forward surge current of 30 A. Electrical characteristics include a maximum instantaneous forward voltage of 1.25 V at 1.5 A, a maximum reverse current of 1 μA at 25 °C, and a maximum reverse recovery time of 140 ns. It is rated for an operating junction temperature range from -55 to +150 °C.

Feature Summary

• Fast reverse recovery time with soft recovery characteristics
• Capable of handling pulse energy in avalanche mode
• Glass passivated junction for low reverse current
• Low profile package suitable for automated placement

Applications

• High frequency rectification in switching mode converters
• Freewheeling applications in inverters

• Telecommunication equipment

Procurement Notes

Verify that the ordering suffix HE3 confirms RoHS compliance and AEC-Q101 qualification as specified in the datasheet. Ensure the component matches the SMA (DO-214AC) package outline dimensions. Confirm the specific voltage rating variant corresponds to the required circuit parameters before integration.

Selection Notes

Select this component for circuits requiring fast recovery and avalanche ruggedness within the SMA footprint. Evaluate thermal resistance values against the expected ambient temperature conditions. Verify that the 200 V reverse voltage rating provides adequate margin for the application's peak inverse voltage requirements.

Part Context

This part belongs to the BYG24 series of fast avalanche rectifiers, which includes variants with different voltage ratings such as 400 V and 600 V. The HE3 suffix indicates an automotive-grade version that meets AEC-Q101 standards. The series utilizes a glass passivated junction technology designed for high reliability in demanding environments.

Replacement Considerations

Direct substitutes within the same family include BYG24GHE3_A/H and BYG24JHE3_A/H, which offer higher voltage ratings of 400 V and 600 V respectively while maintaining identical current and package specifications.
