RS1AHM3_A/I

Single Diodes Overview

The RS1AHM3_A/I is a fast recovery rectifier manufactured by Vishay Semiconductors. It features a single diode configuration housed in the DO-214AC (SMA) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 50 V and conducts a continuous forward current of 1 A. Key electrical characteristics include a maximum forward voltage of 1.3 V, a reverse leakage current of 5 uA, and a typical reverse recovery time of 150 ns. The component operates within a junction temperature range of -55°C to +150°C.

Single Diodes Feature Summary

• Fast recovery performance suitable for high-frequency switching applications
• Glass passivation for reliable operation under thermal stress
• Surface-mount SMA (DO-214AC) packaging for automated assembly

Single Diodes Applications

• High-frequency rectification in power supply circuits

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact manufacturing lot details and compliance status. Ensure the ordering part number matches the required voltage rating and package type. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a low-voltage, high-speed rectification solution is required in a compact surface-mount form factor. The 50 V rating defines the maximum blocking capability, while the 150 ns recovery time distinguishes it from standard general-purpose diodes. Evaluate thermal management requirements based on the 1 A continuous current limit and operating temperature range.

Single Diodes Part Context

This component belongs to the RS1 series of glass-passivated fast recovery rectifiers. The series offers various voltage ratings within the SMA package, allowing designers to standardize on a single footprint for different circuit voltage requirements. The HM3 designation indicates lead-free construction compliant with RoHS directives.

Single Diodes Replacement Considerations

Consult Vishay technical resources for verified cross-references. Substitution requires matching the 50 V reverse voltage, 1 A forward current, SMA package, and fast recovery characteristics.
