SS34HM3_A/I

Single Diodes Overview

The SS34HM3_A/I is a silicon Schottky barrier rectifier manufactured by Vishay Semiconductors. It features a single diode configuration in an SMD/SMT package with DO-214AB-2 (SMC) housing. The device supports a maximum average forward current of 3 A and a repetitive peak reverse voltage of 40 V. Key electrical characteristics include a typical forward voltage of 500 mV, a non-repetitive peak forward surge current of 100 A, and a maximum reverse current of 500 uA. It operates within a temperature range of -55 C to +150 C junction temperature.

Single Diodes Procurement Notes

Verify the suffix 'A/I' against official Vishay documentation to confirm specific tape-and-reel packaging or marking variations compared to standard variants. Ensure the component matches the DO-214AB-2 footprint requirements. Cross-reference the datasheet revision date to validate electrical parameters before integration into production designs.

Single Diodes Selection Notes

Select this component for designs requiring robust performance in low-voltage, high-frequency environments. The Schottky technology offers superior switching speeds compared to standard PN junctions. Verify that the 40 V rating provides sufficient headroom for the specific circuit's peak reverse voltage conditions to ensure long-term reliability.

Single Diodes Part Context

This part belongs to the SS34 series of 3.0 Amp Surface Mounted Schottky Barrier Rectifiers. The series is designed for general-purpose rectification in space-constrained PCB layouts. The HM3 designation indicates lead-free construction compliant with environmental directives, while the A/I suffix typically denotes specific packaging or marking configurations defined by the manufacturer.

Single Diodes Replacement Considerations

Direct replacements must match the 3 A current rating, 40 V reverse voltage, and DO-214AB-2 package. Verify thermal management requirements as forward voltage characteristics may vary between manufacturers. Ensure any substitute maintains equivalent surge current capabilities and reverse leakage specifications.
