BYV29B-400HE3_A/I

Overview

The BYV29B-400HE3_A/I is a general-purpose ultrafast recovery rectifier diode manufactured by Vishay General Semiconductor. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 8 A. The device utilizes a glass passivated chip junction to ensure reliability under high-speed switching conditions. It is housed in a surface-mount TO-263AB (D2PAK) package, designed for efficient thermal dissipation and automated assembly processes.

Feature Summary

• Ultrafast recovery time characteristics for high-frequency operation
• Glass passivated chip junction for enhanced stability
• Low forward voltage drop to minimize conduction losses
• Designed for low switching losses and high efficiency

Applications

• High-frequency DC/DC converters
• Free-wheeling diodes in power supplies
• Snubber circuits in inductive load switching

Procurement Notes

Verify the specific suffix 'A/I' corresponds to the tape-and-reel packaging format if required for your assembly line. Confirm that the component meets the intended environmental specifications for your application. Cross-reference the datasheet revision date to ensure compatibility with your design requirements. Ensure the supplier provides traceability documentation for quality assurance purposes.

Selection Notes

Select this component when an 8 A current rating and 400 V blocking voltage are required in a surface-mount form factor. The TO-263AB package offers superior thermal performance compared to smaller SMD packages. Consider the ultrafast recovery特性 if the circuit operates at frequencies where standard recovery diodes would exhibit excessive reverse recovery charge losses.

Part Context

This part belongs to the BYV29B series of ultrafast recovery diodes from Vishay. The series is characterized by high reliability and consistent electrical parameters across production batches. The 'HE3' designation typically indicates a halogen-free and RoHS-compliant manufacturing process, aligning with modern environmental standards for electronic components.

Replacement Considerations

The BYV29B-400HE3_A/P is a pin-compatible alternative within the same family, differing primarily in packaging configuration. Verify that any substitute maintains identical electrical ratings and package dimensions to ensure seamless integration without PCB redesign.
