BYV29B-300HE3_A/I

Overview

The BYV29B-300HE3_A/I is a high-speed switching diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 300 V and an average forward rectified current of 1 A. The device exhibits a low forward voltage drop of 1.45 V at 1 A and a fast reverse recovery time of 7 ns. It is housed in a compact SOD-123 surface-mount package, designed for efficient performance in high-frequency applications with a junction temperature range from -65°C to 175°C.

Feature Summary

Fast recovery characteristics suitable for high-frequency switching
Low forward voltage drop for improved efficiency
Glass passivated junction for enhanced reliability

Applications

High frequency DC/DC converters
Switching power supplies
Freewheeling diodes
Reverse battery protection circuits

Procurement Notes

Verify the specific suffix HE3_A/I against the manufacturer's latest datasheet to confirm lead-free status and halogen-free compliance. Ensure the ordering part number matches the required packaging format, as variations exist between tape-and-reel and bulk quantities. Cross-reference the component marking code on the physical device with official Vishay documentation to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when a compact SOD-123 footprint is required alongside fast switching speeds. The 300 V rating provides adequate margin for standard low-voltage DC bus applications. Consider the 1 A current limit for load requirements and ensure thermal management aligns with the specified junction temperature limits under expected operating conditions.

Part Context

This diode belongs to the BYV29 series of high-speed switching devices from Vishay. The series utilizes glass passivation technology to ensure robust performance in demanding environments. The SOD-123 package offers space-saving benefits compared to larger through-hole alternatives, making it suitable for modern dense PCB layouts.
