MBR4045CT

Diode Arrays Overview

The MBR4045CT is a dual Schottky barrier rectifier manufactured by SMC Diode Solutions. It features a common cathode configuration housed in a D2PAK surface-mount package. The device supports a maximum repetitive peak reverse voltage of 45 V and an average forward current of 40 A per diode. Key electrical characteristics include a low forward voltage drop of 580 mV at 20 A and a maximum reverse leakage current of 3 mA at 45 V. The component operates within a junction temperature range of -55°C to 150°C.

Diode Arrays Feature Summary

• Schottky barrier technology ensures low power loss and high efficiency during operation.
• Common cathode dual configuration simplifies circuit design for bridge or free-wheeling applications.
• D2PAK surface-mount packaging provides robust thermal performance and reliable mounting.

Diode Arrays Applications

• Low voltage, high frequency inverters
• Free-wheeling rectification circuits
• Polarity protection systems

Diode Arrays Procurement Notes

Verify the specific suffix 'CT' corresponds to the required tape-and-reel packaging format when ordering. Confirm that the D2PAK footprint matches the target PCB layout. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number directly with official distributor catalogs to avoid substitution errors.

Diode Arrays Selection Notes

Select this component for applications requiring high current handling at low voltages where switching speed is less critical than conduction efficiency. The 45 V rating suits 24 V or 36 V DC systems. Consider the thermal resistance of the D2PAK package for heat dissipation requirements. Compare against standard PN junction rectifiers to leverage the lower forward voltage drop advantages of Schottky technology.

Diode Arrays Part Context

This device belongs to the MBR40 series of Schottky rectifiers from SMC Diode Solutions. It shares the same die and electrical specifications as the MBR4045 but differs in packaging and reel configuration. The D2BAK form factor distinguishes it from through-hole alternatives like the TO-220 variants in the same product family.

Diode Arrays Replacement Considerations

The MBR4045 is a direct functional equivalent with identical electrical ratings and pinout. Verify package compatibility before substitution. Other 40 A, 45 V Schottky diodes in D2PAK packages may serve as alternatives if pin configurations match.
