MBR2040CD-HF

Diode Arrays Overview

The MBR2040CD-HF is a Schottky barrier rectifier manufactured by Comchip Technology. It features a dual common cathode configuration housed in a TO-252AA (DPAK) surface-mount package. The device is rated for a repetitive peak reverse voltage of 40V and an average forward rectified current of 20A per element. Key electrical characteristics include a maximum DC blocking voltage of 40V, a typical forward voltage drop of 0.63V at 10A, and a maximum non-repetitive peak forward surge current of 150A. The component operates within a junction temperature range of -55°C to +175°C and complies with RoHS standards.

Diode Arrays Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm package type and compliance status. Ensure the ordering part number matches the required thermal and electrical specifications for the target design. Cross-reference the manufacturer's latest documentation to confirm availability and any recent product changes or obsolescence notices before finalizing procurement.

Diode Arrays Selection Notes

Select this component for designs requiring a dual Schottky rectifier in a compact surface-mount form factor. The 40V rating suits low-voltage DC-DC converters and power supplies. Evaluate the thermal resistance of the TO-252AA package against the expected load current to ensure adequate heat dissipation without excessive junction temperature rise during continuous operation.

Diode Arrays Part Context

This component belongs to the MBR series of Schottky barrier rectifiers from Comchip Technology. The series is designed for general-purpose rectification in low-voltage, high-frequency environments. The 'CD' designation typically indicates the dual common cathode configuration and the TO-252AA package style, distinguishing it from single-element or different package variants within the same voltage and current family.

Diode Arrays Replacement Considerations

Potential substitutes include other dual common cathode Schottky rectifiers with equal or higher current ratings (20A) and voltage ratings (40V) in a TO-252AA package. Verify pinout compatibility and thermal performance when considering alternatives from other manufacturers.
