U1C-E3/5AT

Single Diodes Overview

The U1C-E3/5AT is a surface-mount ultrafast plastic rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a peak repetitive reverse voltage of 200 V and an average forward rectified current of 1 A. The device utilizes the DO-214AC (SMA) package for compact circuit integration. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A and a junction temperature range from -55°C to 150°C. The component exhibits a typical reverse recovery time of 35 ns, ensuring efficient switching performance in high-frequency applications.

Single Diodes Feature Summary

• Ultrafast recovery characteristics enable high-speed switching operations with minimal reverse recovery charge.
• Plastic encapsulation provides mechanical robustness and resistance to physical shock during assembly and operation.
• Low thermal impedance facilitates effective heat dissipation within the compact SMA surface-mount footprint.

Single Diodes Applications

• High-frequency DC-DC converter output rectification
• Free-wheeling diode circuits in power supplies
• Snubber circuits in inductive load protection

Single Diodes Procurement Notes

Verify the obsolete status of this specific part number before initiating procurement processes. Confirm availability through authorized distributors or check for active replacement components listed in official Vishay documentation. Ensure that any substitute parts meet the original electrical specifications and package requirements to maintain system integrity.

Single Diodes Selection Notes

Select this component for designs requiring fast recovery times in low-voltage, medium-current applications. The 200 V rating suits systems operating below this threshold with appropriate safety margins. Consider the DO-214AC package constraints regarding PCB space and thermal management capabilities when integrating into dense layouts.

Single Diodes Part Context

This device belongs to the US1 series of ultrafast rectifiers from Vishay. It shares the same SMA package form factor as other variants in the lineup but is distinguished by its specific 200 V reverse voltage rating. The series is designed for general-purpose high-speed switching applications where small size and fast recovery are critical design parameters.

Single Diodes Replacement Considerations

Official sources indicate the U1C-E3/5AT is obsolete. Direct substitutes may include other Vishay ultrafast rectifiers in the DO-214AC package with matching 200 V and 1 A ratings, such as the US1C-E3/5AT if available, or equivalent parts from other manufacturers meeting the same electrical and mechanical specifications.
