MBR2040CT

Diode Arrays Overview

The MBR2040CT is a dual common cathode Schottky barrier rectifier manufactured by Diodes Incorporated. It features two independent silicon Schottky diodes within a single TO-220AB package, providing a total average forward rectified current of 20 Amperes (10A per device). The component is rated for a maximum repetitive peak reverse voltage of 40 Volts and supports a non-repetitive peak forward surge current of up to 150 Amperes. Designed for high-efficiency applications, it exhibits low forward voltage drop and minimal stored charge, operating reliably across a junction temperature range from -55°C to +150°C.

Diode Arrays Feature Summary

• Dual common cathode configuration integrating two independent Schottky diodes in one package
• Low forward voltage drop characteristic enabling high conversion efficiency
• Majority carrier conduction resulting in extremely low stored charge for fast switching
• Robust thermal performance with high surge current capability

Diode Arrays Applications

• High-frequency DC-DC converters
• Free-wheeling rectification in power supplies
• Polarity protection circuits
• General purpose rectification in low-voltage systems

Diode Arrays Procurement Notes

Verify the specific manufacturer marking and datasheet revision when sourcing, as multiple vendors produce equivalent TO-220AB Schottky rectifiers. Confirm that the received components match the 40V rating and 20A continuous current specifications required for your design. Ensure compliance with RoHS directives if applicable to your assembly process. Cross-reference pinouts carefully to confirm common cathode orientation before integration into PCB layouts.

Diode Arrays Selection Notes

Select this component when a dual-diode solution is required for synchronous rectification or bridge-less PFC topologies. The TO-220AB package offers superior heat dissipation compared to surface-mount alternatives, making it suitable for higher power densities. Consider the 40V reverse voltage rating against peak line transients. Evaluate thermal resistance requirements to ensure the heatsinking strategy maintains junction temperatures within the specified 150°C limit under full load conditions.

Diode Arrays Part Context

This part belongs to the broader category of discrete Schottky barrier rectifiers designed for power management. Unlike standard PN-junction diodes, Schottky devices utilize a metal-semiconductor junction to achieve faster recovery times and lower on-state losses. The dual configuration simplifies board space usage in applications requiring isolated or complementary rectification paths, such as half-bridge drivers or dual-rail power distribution networks.

Diode Arrays Replacement Considerations

Direct substitutes include other 40V, 20A dual common cathode Schottky rectifiers in TO-220AB packages, such as the MBR2040 from alternative manufacturers like Vishay or ON Semiconductor. Verify that replacement parts maintain identical pinout configurations and thermal characteristics to ensure compatibility with existing footprints and cooling solutions.
