MBR2045CTI

Diode Arrays Overview

The MBR2045CTI is a high-efficiency dual Schottky rectifier manufactured by Diodes Incorporated, designed for medium voltage operation in switch mode power supplies and other power converters. It features a common cathode configuration with two independent diode legs housed in a TO-251-3 (TO-251AA) surface-mount package. Each leg supports an average rectified forward current of 10A, totaling 20A, with a peak repetitive reverse voltage rating of 45V. The device exhibits a maximum instantaneous forward voltage drop of 0.65V at +25°C and a maximum reverse leakage current of 0.1mA at +25°C. It operates up to a junction temperature of +150°C and includes a guard-ring structure for stress protection.

Diode Arrays Feature Summary

• Low forward voltage characteristic reduces conduction losses
• High surge current capability handles transient loads
• Guard-ring design provides enhanced stress protection
• Lead-free finish compliant with RoHS directives

Diode Arrays Applications

• Power supply output rectification
• Power management circuits
• Instrumentation systems

Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and packing method. The 'I' suffix typically indicates a specific tape-and-reel or tube configuration distinct from standard bulk packaging. Confirm compliance requirements such as halogen-free status if required by your manufacturing standards. Ensure the component matches the intended thermal management strategy given its surface-mount form factor.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low switching losses and minimal noise in high-frequency applications. The dual common cathode arrangement simplifies layout for synchronous rectification or polarity protection schemes. Consider the thermal resistance characteristics of the TO-251-3 package and ensure adequate PCB copper area for heat dissipation to maintain performance within the specified junction temperature limits.

Diode Arrays Part Context

This part belongs to the MBR2045C series of high-efficiency power Schottky rectifiers from Diodes Incorporated. The series is engineered for medium voltage operations where efficiency and speed are critical. The MBR2045CTI variant specifically utilizes the TO-251-3 package, offering a compact solution compared to through-hole alternatives while maintaining similar electrical performance metrics for general-purpose power conversion tasks.

Diode Arrays Replacement Considerations

Direct replacements include MBR2045CT-E1 and MBR2045CT-G1 from the same manufacturer family, which share identical electrical specifications but may differ in packaging format or environmental compliance markings. Verify pinout compatibility and thermal characteristics before substituting.
