MBRD640CTT4H

Diode Arrays Overview

The MBRD640CTT4H is a dual Schottky barrier rectifier manufactured by onsemi, featuring a common cathode configuration. It is designed for high-efficiency power conversion applications requiring low forward voltage drop and fast switching speeds. The device utilizes silicon technology to ensure robust performance under varying thermal conditions. Key electrical characteristics include a maximum repetitive peak reverse voltage of 40 V and a continuous forward current rating of 6 A per anode. The component is housed in a D2PAK-3 (TO-263-3) surface-mount package, facilitating automated assembly and efficient heat dissipation through the exposed tab.

Diode Arrays Feature Summary

• Low forward voltage drop minimizes conduction losses and improves overall system efficiency.
• Fast switching action reduces reverse recovery charge, lowering electromagnetic interference.
• Common cathode configuration simplifies circuit design for full-wave or synchronous rectification.

Diode Arrays Applications

• DC-DC converters in portable electronics
• Power supplies for consumer appliances
• Adapters and chargers for mobile devices

Diode Arrays Procurement Notes

Verify the exact suffix 'T4H' against official onsemi documentation to confirm tape-and-reel specifications and lot traceability requirements. Ensure compatibility with standard D2PAK footprints during PCB layout. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when designing circuits that require a balance between high current handling and low voltage loss. The 40 V rating suits low-voltage DC bus applications. Consider the thermal resistance of the D2PAK package for adequate heatsinking if operating near maximum current limits. Compare with similar series parts like MBRD640CT for pin-compatible alternatives if supply constraints exist.

Diode Arrays Part Context

This part belongs to onsemi's MBRD series of dual Schottky rectifiers, engineered for general-purpose rectification in compact power modules. The series is characterized by its reliability in high-frequency switching environments. The MBRD640CTT4H variant specifically targets cost-sensitive applications where space-saving surface-mount packaging is critical for miniaturization.

Diode Arrays Replacement Considerations

Check for direct substitutes such as MBRD640CTT4G, ensuring package and electrical parameters match. Verify that any replacement maintains the same common cathode configuration and thermal performance characteristics to avoid redesigning the cooling solution.
