SL22HE3_A/I

Single Diodes Overview

The SL22HE3_A/I is a surface-mount Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a DO-214AA (SMB) package and is designed for low voltage, high frequency applications. The device offers an average forward current of 2.0 A with a maximum repetitive reverse voltage ranging from 20 V to 30 V depending on the specific variant within the series. It exhibits a very low forward voltage drop of 0.32 V and supports a high surge current capability of 100 A. The component operates within a junction temperature range up to 125 °C and meets RoHS 2002/95/EC standards.

Single Diodes Feature Summary

• Guardring structure provides enhanced overvoltage protection capabilities
• Low profile package design ideal for automated placement processes
• Matte tin plated leads ensure solderability per J-STD-002 and JESD22-B102 standards

Single Diodes Applications

• Low voltage high frequency inverters
• Freewheeling diode circuits
• DC-to-DC converters
• Polarity protection applications

Single Diodes Procurement Notes

Verify the specific voltage rating required for your application, as the SL22 series includes variants with different maximum repetitive reverse voltages (e.g., 20V, 30V). Confirm that the DO-214AA (SMB) package size fits your PCB layout constraints. Ensure the supplier provides documentation confirming compliance with RoHS 2002/95/EC and WEEE 2002/96/EC directives if environmental compliance is a project requirement.

Single Diodes Selection Notes

Select this component when a surface-mount Schottky rectifier with low forward voltage drop is needed for efficiency in power conversion circuits. The 2A average current rating suits moderate power applications. Consider the thermal management requirements given the 125 °C maximum junction temperature limit. Verify that the chosen voltage variant matches the circuit's peak inverse voltage demands to ensure reliable operation under all conditions.

Single Diodes Part Context

This part belongs to Vishay's general semiconductor diode division portfolio, specifically within the Schottky barrier rectifier category. The 'E3' suffix indicates lead-free construction with matte tin plating, while 'HE3' typically denotes high reliability grades qualified for automotive standards like AEC-Q101. The SMB package is a standard surface-mount form factor widely used in consumer and industrial electronics for space-constrained designs requiring efficient rectification.
