Diode Arrays Procurement Notes

Verify the specific suffix HE3 indicates AEC-Q101 qualification and compliance with JESD 201 class 2 whisker testing standards. Confirm the package type matches the required PCB footprint for the TO-263AB configuration. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values under expected load conditions.

Diode Arrays Selection Notes

Select this component when high-frequency switching and low forward voltage are critical for system efficiency. The dual common cathode configuration allows for efficient bridgeless PFC or synchronous rectification topologies. Verify that the 50 V reverse voltage rating exceeds the maximum circuit transient voltages to ensure reliable operation without breakdown.

Diode Arrays Part Context

This part belongs to the MBRB25HxxCT series of dual Schottky rectifiers designed for high-performance power conversion. The series offers various voltage ratings including 35 V, 45 V, 50 V, and 60 V options within the same physical package family. The HE3 variant specifically targets automotive and industrial applications requiring strict reliability standards.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay MBRB25HxxCTHE3 variants for different voltage ratings such as MBRB25H45CTHE3 or MBRB25H60CTHE3 if voltage requirements change. Ensure any substitute maintains the TO-263AB package and AEC-Q101 qualification if automotive grade is required.
