Diode Arrays Procurement Notes

This component has been officially declared End-of-Life (EOL) by the manufacturer as of December 9, 2016. Verification of availability requires checking authorized distributors for remaining stock or approved substitute part numbers. Ensure that any replacement components meet the original electrical specifications and package dimensions to maintain circuit integrity.

Diode Arrays Selection Notes

Select this component for low-voltage, high-current rectification where low forward voltage drop is critical for minimizing power loss. The TO-220-3 package offers robust thermal performance for through-hole mounting. Verify that the 45 V reverse voltage rating exceeds the peak inverse voltage in the application circuit to ensure reliable operation under transient conditions.

Diode Arrays Part Context

Part of the MBR20HxxCT series of dual Schottky barrier rectifiers designed for general-purpose power conversion. The E3 suffix indicates lead-free termination and RoHS compliance. The /45 suffix denotes the specific voltage rating variant within the family. This series is engineered for high-frequency operation and improved efficiency compared to standard silicon rectifiers.

Diode Arrays Replacement Considerations

Officially documented similar substitutes include V30D45C-M3/I and STPS2045CT. Verify pinout compatibility and thermal characteristics when substituting. Ensure the replacement device meets the same 45 V reverse voltage and 10 A current requirements.
