U2D-M3/52T

Single Diodes Overview

The U2D-M3/52T is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 200 V and an average rectified forward current (Io) of 2 A. The device utilizes the DO-214AA (SMB) surface-mount package. Key electrical parameters include a maximum forward voltage (Vf) of 1.3 V at 2 A, a reverse leakage current of 5 µA at 200 V, and a reverse recovery time (trr) of 2 µs. The junction capacitance is specified as 15 pF at 4 V and 1 MHz. The component operates within a junction temperature range of -65°C to 175°C.

Single Diodes Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm compliance with RoHS3 standards and environmental regulations. Ensure the ordering part number matches the required packaging format, such as tape and reel or cut tape, as indicated in the manufacturer's datasheet. Cross-reference the component code with authorized distributor catalogs to validate authenticity and traceability before procurement.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 2 A continuous current capacity are required in a surface-mount form factor. The standard recovery characteristics make it appropriate for lower-frequency switching applications where fast recovery is not critical. Compare the thermal resistance and package size against alternative SMB diodes to ensure compatibility with the target PCB layout and thermal management strategy.

Single Diodes Part Context

This component belongs to the U-series of standard recovery rectifiers from Vishay. These devices are designed for high-reliability applications requiring robust performance in compact packages. The series typically offers consistent electrical characteristics across various voltage ratings, providing designers with standardized options for power conversion and rectification tasks in consumer and industrial electronics.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers for U2D-M3/52T were not identified in the provided source material. Verify compatibility with equivalent SMB-packaged 200 V 2 A standard recovery diodes from other manufacturers by comparing pinout, voltage ratings, and current specifications.
