Diode Arrays Procurement Notes

Verify authenticity by purchasing exclusively from MCC or authorized distributors due to counterfeiting risks. Confirm the specific DFN5060 package variant matches design requirements. Ensure compliance with automotive qualification standards if used in critical applications. Check for updated datasheet revisions before finalizing component selection.

Diode Arrays Selection Notes

Select this component for applications demanding low forward voltage drop and high surge current capability in a small footprint. The DFN5060 package offers improved thermal performance compared to traditional packages. Consider the 45V rating when designing for automotive battery voltages. Verify PCB copper pad areas match datasheet recommendations for optimal heat dissipation.

Diode Arrays Part Context

This part belongs to the MBRP series of Schottky rectifiers from Micro Commercial Components. It utilizes silicon technology optimized for high-frequency operation. The Q suffix indicates automotive qualification, while TP denotes tape-and-reel packaging. The device integrates two independent diodes in a single compact package to save board space.

Diode Arrays Replacement Considerations

Direct substitutes must share the DFN5060 package, 45V rating, and 3A per diode current capacity. Verify pinout compatibility as pins 1-4 are Anode and 5-8 are Cathode. Ensure replacement parts meet AEC-Q101 standards if automotive use is required. Thermal resistance values should be comparable to maintain circuit reliability.
