BYG24JHE3_A/I

Overview

The BYG24JHE3_A/I is a fast avalanche surface-mount rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes a glass passivated junction within a low-profile DO-214AC (SMA) package, designed for automated placement. The device supports an average forward current of 1.5 A and withstands repetitive peak reverse voltages ranging from 200 V to 600 V depending on the specific suffix variant. Key electrical characteristics include a maximum reverse leakage current of 1.0 µA, a typical forward voltage of 1.25 V, and a fast reverse recovery time of 140 ns with a soft recovery characteristic.

Feature Summary

• Fast reverse recovery time with soft recovery characteristics suitable for high-frequency applications
• Glass passivated junction providing low reverse current and high reliability
• Avalanche rated capability for robust performance in switching environments
• Low profile package ideal for automated surface-mount placement processes

Applications

• High frequency rectification in switching mode converters
• Freewheeling diode applications in inverters
• Consumer electronics power supplies
• Computer equipment power circuits
• Automotive electronic systems
• Telecommunication infrastructure power modules

Procurement Notes

Verify the specific voltage rating suffix (e.g., J for 400V) against the design requirements, as the base model covers a range up to 600V. Confirm compliance with RoHS Directive 2002/95/EC and WEEE 2002/96/EC standards. Ensure the DO-214AC (SMA) footprint matches the PCB layout. Check for AEC-Q101 qualification if automotive grade reliability is required for the specific sub-part number.

Selection Notes

Select this component for designs requiring fast switching speeds and soft recovery to minimize electromagnetic interference. The DO-214AC package offers a compact solution for space-constrained boards. Consider the thermal management capabilities given the 150°C maximum junction temperature. Evaluate the 30 A non-repetitive peak forward surge current against potential inrush conditions in the target application circuit.

Part Context

This part belongs to Vishay's BYG series of fast avalanche rectifiers. These devices are engineered to replace slower standard recovery diodes in modern high-efficiency power conversion topologies. The series emphasizes reliability through glass passivation and meets stringent automotive qualification standards when specified, making it suitable for demanding industrial and consumer markets.

Replacement Considerations

Substitute only with verified equivalent part numbers from official manufacturer cross-reference lists. Generic replacements may lack the specific avalanche rating or soft recovery characteristics documented for this component.
