Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm compliance requirements. The HE3 designation indicates RoHS compliance and AEC-Q101 qualification. Confirm that the D2PAK package variant matches the intended PCB footprint and thermal management strategy. Ensure the component meets the required environmental standards for the target application before finalizing procurement.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for space-constrained designs. The D2PAK package offers lower thermal resistance compared to through-hole alternatives. Consider the 100 V rating and 20 A total current capacity relative to the circuit load. Verify that the operating junction temperature will not exceed the specified maximum limits under worst-case conditions.

Diode Arrays Part Context

This part belongs to the MB20HxxCT series of dual common cathode Schottky rectifiers from Vishay. It shares architectural similarities with the MF20H100CT, which utilizes an ITO-220AB through-hole package. Both variants offer identical electrical characteristics but differ in mounting style and thermal performance metrics due to their distinct physical packages.

Diode Arrays Replacement Considerations

The MF20H100CTHE3_B/P serves as a direct functional equivalent within the same family, differing only in its ITO-220AB through-hole package. Substitution requires verification of mechanical fit and thermal dissipation capabilities on the printed circuit board.
