ESH2DHE3/52T

Single Diodes Overview

The Vishay ESH2DHE3/52T is a surface-mount ultrafast plastic rectifier in the SMB (DO-214AA) package. It features a glass passivated pellet chip junction and supports a maximum repetitive peak reverse voltage of 200 V with an average forward rectified current of 2.0 A. The device exhibits a maximum instantaneous forward voltage of 0.93 V at 2 A and a typical reverse recovery time of 25 ns to 55 ns depending on temperature. It operates within a junction temperature range of -55 °C to +175 °C, meets MSL level 1 requirements, and carries AEC-Q101 qualification.

Single Diodes Feature Summary

• Automotive electronic systems requiring qualified components

Single Diodes Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number and datasheet revision against official Vishay documentation. Confirm that the specific ordering code matches the required voltage rating and packaging format. Ensure compliance with RoHS directives and check for any region-specific distribution restrictions before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating is required alongside a 2 A continuous current capacity. The ultrafast recovery profile makes it suitable for high-frequency environments where low stored charge is critical. Verify thermal management capabilities align with the specified junction temperature limits and ambient operating conditions.

Single Diodes Part Context

This device belongs to the ESH2 series of ultrafast rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different voltage ratings, such as the ESH2B and ESH2C, sharing identical physical dimensions and electrical performance profiles except for the blocking voltage specifications. All members utilize the standard SMB surface-mount package.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay ESH2 series parts like ESH2BHE3 or ESH2CHE3 if lower voltage ratings are acceptable. Cross-manufacturer replacements must match the 2 A current, 200 V reverse voltage, and SMB package constraints while verifying equivalent recovery times.
