1N5821-E3/54

Overview

The Vishay 1N5821-E3/54 is a Schottky barrier plastic rectifier in the DO-201AD package. It features a maximum repetitive peak reverse voltage of 30 V and a maximum average forward rectified current of 3.0 A at 95 °C lead temperature. The device exhibits a maximum instantaneous forward voltage of 0.500 V at 3.0 A and supports a peak forward surge current of 80 A. Operating junction and storage temperatures range from -65 to +125 °C.

Feature Summary

• Guardring structure provides overvoltage protection
• Extremely fast switching with low conduction losses
• High forward surge capability for robust operation

Applications

• Low voltage high frequency inverters
• Freewheeling applications
• DC/DC converters
• Polarity protection circuits

Procurement Notes

Verify the E3 suffix confirms RoHS compliance and JESD 201 class 1A whisker test results. Confirm the /54 package code matches the required 13-inch paper tape and reel delivery mode. Ensure the component meets commercial grade specifications for the intended operating environment.

Selection Notes

Select this component when a 30 V blocking voltage and 3 A continuous current rating are required. The DO-201AD through-hole package suits standard PCB mounting. Consider the thermal resistance characteristics for heat dissipation requirements in the specific circuit layout.

Part Context

This part belongs to the Vishay 1N582x series of Schottky Barrier Plastic Rectifiers, which includes variants rated for 20 V (1N5820) and 40 V (1N5822). All members share identical mechanical data, including the DO-201AD case and matte tin plated leads, differing primarily in their voltage ratings and corresponding forward voltage drops.

Replacement Considerations

Direct substitutes within the same Vishay series include the 1N5820-E3/54 and 1N5822-E3/54. Verify that alternative manufacturers' equivalents match the 30 V reverse voltage and 3 A forward current specifications.
