RS2KHE3/52T

Single Diodes Overview

The RS2KHE3/52T is a general-purpose fast recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V maximum repetitive reverse voltage and a 1.5 A average forward rectified current rating. The device utilizes a DO-214AA (SMB) surface-mount package. Key electrical characteristics include a typical reverse recovery time of 75 ns and a maximum non-repetitive peak surge current of 40 A. It operates within a junction temperature range of -65°C to +175°C and complies with RoHS 3 standards.

Single Diodes Feature Summary

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm package type and compliance status. Ensure the ordering part number matches the required reverse voltage and current ratings for the target application. Cross-reference datasheet revisions to confirm pinout consistency and material composition changes. Confirm availability through authorized distributors as lead times may vary based on manufacturing location.

Single Diodes Selection Notes

Select this component when high reverse voltage blocking capability is required alongside moderate current handling. The fast recovery characteristic makes it suitable for frequencies exceeding standard rectifier limits. Consider the SMB package dimensions for PCB layout constraints. Evaluate thermal management requirements given the 175°C junction limit. Compare against similar Vishay series parts if lower voltage or higher current options are needed.

Single Diodes Part Context

This component belongs to the RS2K family of fast recovery rectifiers from Vishay. These devices are designed for use in applications requiring rapid switching speeds and high reliability. The E3 suffix indicates lead-free termination and RoHS compliance. The /52T suffix typically denotes tape and reel packaging configuration for automated assembly processes.

Single Diodes Replacement Considerations

Official substitutes within the Vishay portfolio include other RS2K series variants with adjusted voltage ratings. Verify compatibility regarding reverse recovery time and forward voltage drop when cross-referencing with competitor fast recovery diodes. Ensure package footprint and pin configuration match exactly to avoid PCB redesign.
