MBR20100CT-BP

Diode Arrays Overview

The MBR20100CT-BP is a Schottky Barrier Rectifier manufactured by Micro Commercial Components (MCC). It features a dual common cathode configuration housed in a TO-220AB package. The device supports an average forward current of 20A at a case temperature of 120°C and withstands a maximum repetitive peak reverse voltage of 100V. Key electrical characteristics include a maximum instantaneous forward voltage of 0.85V at 20A and 25°C, and a peak forward surge current capability of 150A for an 8.3ms half-sine wave. The component operates within a junction temperature range of -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the authenticity of the MBR20100CT-BP by purchasing directly from Micro Commercial Components or their authorized distributors. Counterfeit components are prevalent; unauthorized sources lack traceability and quality assurance. Confirm that the ordering suffix indicates compliance with lead-free requirements and check for specific halogen-free availability if required by adding the appropriate suffix.

Diode Arrays Selection Notes

Select this component for power supply designs requiring low forward voltage drop to minimize conduction losses. Ensure the thermal management system maintains the case temperature below 120°C to sustain the rated 20A current. Verify that the circuit's peak reverse voltage does not exceed the 100V rating. Consider the TO-220AB package dimensions for PCB layout and heatsinking compatibility.

Diode Arrays Part Context

This part belongs to the MBR2020CT through MBR20100CT series of Schottky Barrier Rectifiers. The series offers various voltage ratings from 20V to 100V while maintaining a consistent 20A current capacity. All devices in this family share similar physical packaging and thermal characteristics, differing primarily in their breakdown voltage specifications.

Diode Arrays Replacement Considerations

Other parts within the MBR2020CT to MBR20100CT series may serve as substitutes if voltage ratings align. Cross-brand replacements must match the TO-220AB footprint, 20A current rating, and 100V reverse voltage. Verify equivalent forward voltage and thermal resistance parameters before implementation.
