MURB1020CTTRL

Overview

The MURB1020CTTRL is a dual common cathode ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes FRED Pt technology to achieve high efficiency and low switching losses. The device features a TO-263AB (D2PAK) surface-mount package with three terminals. Key electrical characteristics include a repetitive peak reverse voltage of 200V, an average forward current of 5A per leg, and a maximum non-repetitive peak forward surge current of 140A. The component is designed for high-frequency operation in power conversion applications.

Feature Summary

• FRED Pt technology for fast recovery and low reverse recovery charge
• Guard ring structure for enhanced ruggedness and long-term reliability
• Low thermal resistance for efficient heat dissipation
• Lead-free plating compliant with RoHS directives

Applications

• High frequency DC/DC converters
• Switching power supplies
• Free-wheeling diodes
• Reverse battery protection circuits

Procurement Notes

Verify the specific suffix 'TRL' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation as Vishay General Semiconductor - Diodes Division. Ensure the package type matches the required TO-263AB footprint for PCB layout compatibility. Check for lead-free compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component for applications requiring fast switching speeds and low reverse recovery charge. The 200V rating suits low-voltage DC-DC conversion stages. The D2PAK package offers higher current handling than smaller SMD packages while maintaining surface-mount convenience. Consider thermal management requirements given the 5A continuous current rating per element.

Part Context

This part belongs to the MURB series of ultrafast rectifiers from Vishay. It is functionally similar to other FRED Pt devices but optimized for specific voltage and current combinations. The dual common cathode configuration allows for use in half-bridge or synchronous rectifier topologies without requiring external diodes.

Replacement Considerations

Cross-reference with MURB1020CT for loose tube versions. Verify pinout compatibility with existing designs before substitution. Ensure thermal performance meets system requirements when replacing with alternative manufacturers' parts.
