Diode Arrays Procurement Notes

Verify the specific suffix HE3 confirms AEC-Q101 qualification and JESD 201 class 2 whisker test compliance. Confirm the /45 designation aligns with tube delivery packaging requirements. Ensure thermal management design accounts for the specified junction-to-case thermal resistance values under actual operating loads.

Diode Arrays Selection Notes

Select this component when designing circuits requiring dual common cathode configurations with high surge current tolerance. The 50 V rating suits low-voltage output stages where minimizing conduction loss is critical. Verify that the TO-220AB footprint matches the PCB layout constraints and that heatsinking strategies accommodate the thermal dissipation needs at maximum load currents.

Diode Arrays Part Context

This part belongs to the MBR25HxxCT family of dual Schottky rectifiers from Vishay. The series encompasses various voltage ratings ranging from 35 V to 60 V. The HE3 suffix indicates RoHS compliance and automotive qualification, distinguishing it from commercial grade variants. The TO-220AB package provides a balance of current handling capacity and mounting flexibility for through-hole assembly.

Diode Arrays Replacement Considerations

Cross-reference with other Vishay MBR25H50CT variants to verify package compatibility and electrical parameter alignment. Ensure substitute components maintain equivalent AEC-Q101 qualification if automotive usage is required. Validate that alternative packages do not alter thermal resistance or pinout configurations.
