RS3A-E3/9AT

Single Diodes Overview

The RS3A-E3/9AT is a fast recovery rectifier manufactured by Vishay Semiconductors. It features a maximum average forward rectified current of 3.0 A and a repetitive peak reverse voltage of 50 V. The device exhibits a typical reverse recovery time of 150 ns and a non-repetitive peak forward surge current capability of 100 A. It utilizes a glass passivated junction construction for enhanced reliability. The component is housed in an SMC (DO-214AB) surface-mount package, designed for efficient thermal performance and compact circuit board layouts.

Single Diodes Feature Summary

• Glass passivated junction construction ensures high reliability and stability under varying operating conditions.
• Fast recovery characteristics with low reverse recovery time support high-frequency switching applications.
• Surface-mount SMC package design facilitates automated assembly and reduces footprint requirements.

Single Diodes Applications

• High-frequency rectification in power supply circuits
• Free-wheeling diode implementation in inductive load protection
• DC-DC converter output rectification stages

Single Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required packaging formats. Confirm RoHS compliance status and REACH SVHC declarations prior to integration into regulated assemblies. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and traceability. Ensure storage conditions align with moisture sensitivity level requirements specified in the technical documentation.

Single Diodes Selection Notes

Select this component when a 50 V rating and 3 A continuous current capacity are sufficient for the target application. Consider the 150 ns reverse recovery time for suitability in moderate-speed switching environments. Evaluate the SMC package dimensions against available PCB space constraints. Compare thermal dissipation capabilities with alternative packages if higher current densities are anticipated in the design.

Single Diodes Part Context

This device belongs to the RS3x series of fast recovery rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current handling and package form factors. The RS3A variant specifically targets low-voltage, high-current applications requiring rapid switching performance. It complements other components in the same family that provide higher voltage blocking capabilities for different power system architectures.

Single Diodes Replacement Considerations

The RS3A-E3/57T is documented as an alias or equivalent variant within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure that any replacement maintains the same package type and mounting specifications to avoid mechanical redesign efforts.
