MBRD650CTT4G

Diode Arrays Overview

The MBRD650CTT4G is a Schottky barrier rectifier manufactured by onsemi, featuring a dual common cathode configuration in a DPAK-3 surface-mount package. It supports an average forward current of 6 A and offers reverse voltage ratings ranging from 20 V to 60 V, with the specific '650' suffix indicating a 50 V repetitive peak reverse voltage capability. The device utilizes silicon technology and is designed for extremely fast switching applications, characterized by low forward voltage drop and minimal reverse recovery charge.

Diode Arrays Feature Summary

• Schottky barrier construction ensures extremely fast switching speeds and low power losses
• Dual common cathode design integrates two independent rectifiers in a single compact package
• Lead-free finish and halogen-free composition comply with environmental standards

Diode Arrays Applications

• Switching power supplies
• Inverter circuits
• Free wheeling diode applications

Diode Arrays Procurement Notes

Verify the exact reverse voltage rating required for the application, as the MBRD650CTT4G belongs to a series covering 20V to 60V options. Confirm that the DPAK-3 package thermal characteristics meet the system's heat dissipation requirements for continuous 6A operation. Ensure compatibility with surface-mount assembly processes and check for specific automotive or industrial qualification needs if applicable to the end product.

Diode Arrays Selection Notes

Select this component when high-frequency switching efficiency is critical due to its Schottky technology. The dual common cathode arrangement simplifies circuit layout for bridgeless PFC or synchronous rectification topologies. Consider the thermal resistance of the DPAK-3 package and ensure adequate PCB copper area for heat spreading to maintain reliability under full load conditions.

Diode Arrays Part Context

This part is part of onsemi's SWITCHMODE family of power rectifiers, designed specifically for high-efficiency power conversion. It complements other variants in the MBRD6xxCT series, which share the same physical footprint and current handling capabilities but differ in reverse voltage blocking levels. These devices are engineered to replace slower standard recovery diodes in modern compact power designs.

Diode Arrays Replacement Considerations

Direct substitutes within the same series include MBRD620CTT4G (20V), MBRD630CTT4G (30V), MBRD640CTT4G (40V), and MBRD660CTT4G (60V). When replacing, ensure the new part's reverse voltage rating exceeds the maximum circuit transient voltages. Verify that the thermal performance and pinout remain identical to avoid PCB redesign.
