SS1H9HE3_B/I

Single Diodes Overview

The SS1H9HE3_B/I is a single Schottky rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a silicon construction housed in an SMA (DO-214AC) surface-mount package. The device supports a maximum repetitive reverse voltage of 90 V and conducts an average forward current of 1 A. Key electrical characteristics include a maximum forward voltage of 860 mV at 1 A, a peak forward surge current capability of 50 A, and a low reverse leakage current of 1 uA. It operates within a junction temperature range of -65°C to +175°C.

Single Diodes Procurement Notes

Verify the specific suffix B/I against official Vishay documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the DO-214AC footprint requirements for your PCB layout. Cross-reference the RoHS and REACH compliance details directly from the manufacturer's datasheet before finalizing procurement orders.

Single Diodes Selection Notes

Select this component when a 90 V rating is required for 1 A applications in space-constrained designs. The SMA package offers a balance between current handling and board area efficiency. Consider the 175°C junction temperature limit for high-thermal environments where standard diodes may fail.

Single Diodes Part Context

This part belongs to the SS1H series of Schottky rectifiers from Vishay. These devices are designed to replace conventional p-n junction rectifiers in applications requiring higher efficiency and faster switching speeds. The series is widely used in consumer electronics and industrial power supplies.

Single Diodes Replacement Considerations

Consult Vishay's official substitution guide for verified equivalents. Generic replacements must match the 90 V reverse voltage, 1 A current rating, and SMA package dimensions to ensure mechanical and electrical compatibility.
