1N5818-E3/54

Overview

The Vishay 1N5818-E3/54 is a Schottky Barrier Plastic Rectifier featuring a single silicon junction in a DO-41 (DO-204AL) axial package. It supports a maximum average forward rectified current of 1.0 A and a maximum repetitive peak reverse voltage of 30 V. The device exhibits a maximum instantaneous forward voltage of 0.550 V at 1.0 A and 0.875 V at 3.1 A, with a typical junction capacitance of 110 pF. It operates within a temperature range of -65 to +125 °C and withstands a peak forward surge current of 25 A.

Feature Summary

• Guardring structure provides overvoltage protection
• Extremely fast switching with negligible switching losses
• Low forward voltage drop for high efficiency
• Matte tin plated leads are solderable per J-STD-002

Applications

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

Procurement Notes

Verify the E3 suffix confirms RoHS compliance and commercial grade status. Confirm the /54 package code matches the required 13-inch paper tape and reel delivery mode. Ensure the ordering part number aligns with the specific 30 V rating requirements for your circuit design.

Selection Notes

Select this component when low conduction losses and fast switching speeds are critical. The 30 V reverse voltage rating suits low voltage power supplies. Verify thermal management capabilities against the specified junction-to-lead thermal resistance for your specific mounting configuration.

Part Context

This device belongs to the 1N581x series of Schottky Barrier Rectifiers manufactured by Vishay General Semiconductor. It shares mechanical dimensions and feature sets with the 1N5817 and 1N5819 variants, differentiated primarily by their respective reverse voltage ratings of 20 V, 30 V, and 40 V.

Replacement Considerations

Compatible substitutes include the 1N5817 and 1N5819 from the same Vishay series, provided the voltage ratings meet the application's reverse blocking requirements.
