SSB44HE3_A/H

Single Diodes Overview

The SSB44HE3_A/H is a silicon Schottky rectifier from Vishay, designed for surface mount applications in the DO-214AA (SMB) package. It features a maximum repetitive reverse voltage of 40 V and an average forward current rating of 4 A. The device exhibits a typical forward voltage drop of 420 mV at 4 A and supports a surge current of 100 A. It operates within a junction temperature range of -65°C to +150°C and holds AEC-Q101 automotive qualification.

Single Diodes Feature Summary

• Guardring technology provides enhanced overvoltage protection capabilities
• Low profile surface mount design facilitates automated placement processes
• High efficiency operation achieved through very low forward voltage drop characteristics

Single Diodes Applications

• Free-wheeling diodes in low voltage high frequency inverters
• DC-to-DC converter circuits
• Polarity protection applications

Single Diodes Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the HE3 suffix indicates high reliability grade compliant with AEC-Q101 standards. Ensure storage conditions maintain moisture sensitivity level 1 integrity prior to soldering. Validate RoHS compliance documentation matches current regulatory requirements for your target market.

Single Diodes Selection Notes

Select this component when automotive-grade reliability is required for 40 V systems. The SMB package offers higher current density compared to smaller footprints. Consider the 150°C junction temperature limit for thermal management calculations. Verify that the 4 A continuous current rating meets peak load demands without exceeding thermal boundaries during operation.

Single Diodes Part Context
