MBR1045CT

Diode Arrays Overview

The MBR1045CT is a Schottky barrier rectifier manufactured by SMC Diode Solutions, designed for high-efficiency power conversion. It features a common cathode dual configuration housed in a TO-263AB (D2PAK) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 45V and an average forward rectified current of 10A per diode. Key electrical characteristics include a low forward voltage drop of 840mV at 7.5A and a maximum reverse leakage current of 1mA at 45V. It operates within a junction temperature range of -55°C to 150°C.

Diode Arrays Feature Summary

• Schottky barrier construction ensures majority carrier conduction for minimal switching losses.
• Common cathode dual configuration simplifies circuit design for synchronous rectification.
• Guard ring technology provides enhanced protection against overvoltage conditions.

Diode Arrays Applications

• Free-wheeling diodes in DC-DC converters
• Reverse battery protection circuits
• Low voltage, high frequency inverters

Diode Arrays Procurement Notes

Verify the specific manufacturer datasheet revision when sourcing, as packaging suffixes may indicate variations in reel specifications or tape-and-reel quantities. Confirm that the TO-263AB footprint matches the target PCB layout. Ensure compliance with RoHS directives if required by the end application standards.

Diode Arrays Selection Notes

Select this component for applications requiring low forward voltage drop to maximize efficiency in low-voltage power supplies. The D2PAK package offers superior thermal dissipation compared to smaller surface-mount options. Consider the 45V rating to ensure adequate headroom against voltage spikes in the specific circuit topology.

Diode Arrays Part Context

This part belongs to the MBR1045 series of Schottky rectifiers from SMC Diode Solutions. It shares functional similarities with other models in the lineup but is distinct due to its specific 10A current rating and dual common cathode arrangement. The TO-263AB package differentiates it from lower-power variants using smaller footprints.

Diode Arrays Replacement Considerations

Cross-reference with MBRB1545CTTR for higher current capacity in similar packages. Verify pinout compatibility before substituting with devices from other manufacturers such as Taiwan Semiconductor or MCC.
