SS1H9-E3/5AT

Single Diodes Overview

The SS1H9-E3/5AT is a single Schottky rectifier manufactured by Vishay Semiconductors, housed in the SMA (DO-214AC) surface-mount package. It features a silicon construction with a maximum repetitive reverse voltage of 90 V and an average forward current rating of 1 A. The device exhibits a typical forward voltage of 860 mV at rated current and a low reverse leakage current of 1 uA. It supports a peak non-repetitive forward surge current of 50 A and operates within a junction temperature range of -65 °C to +175 °C.

Single Diodes Feature Summary

• Utilizes Schottky barrier technology for high switching efficiency
• Engineered for low forward voltage drop to minimize power loss
• Designed for high reliability in compact surface-mount applications

Single Diodes Applications

• DC-DC converters
• Power supply circuits
• Reverse polarity protection

Single Diodes Procurement Notes

Verify the specific suffix E3/5AT against official Vishay documentation to confirm RoHS compliance and reel packaging specifications. Ensure the SMA (DO-214AC) footprint matches the target PCB design. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm that the 90 V rating aligns with the system's peak inverse voltage requirements.

Single Diodes Selection Notes

Select this component when a low-loss Schottky rectification solution is required in a small SMA package. The 90 V breakdown voltage suits intermediate voltage rails where standard silicon diodes would incur higher conduction losses. The wide operating temperature range up to 175 °C allows for robust performance in thermally constrained environments without derating.

Single Diodes Part Context

This device belongs to the SS1H series of high-efficiency Schottky rectifiers from Vishay. The series is characterized by its use of silicon carbide metal-silicon technology to achieve superior performance compared to conventional silicon rectifiers. The SMA package provides a cost-effective surface-mount option for consumer and industrial electronics requiring reliable rectification.

Single Diodes Replacement Considerations

Direct substitutes include other Vishay SS1H9 variants with compatible suffixes. Equivalent parts from other manufacturers must match the 90 V rating, 1 A current capacity, and SMA footprint while maintaining comparable forward voltage characteristics.
