Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm compliance requirements. The HE3 suffix indicates RoHS compliance and adherence to JESD 201 class 2 whisker test standards. Confirm package type and thermal characteristics match the intended circuit design before procurement.

Diode Arrays Selection Notes

Select this component for applications requiring high efficiency and low forward voltage drop at 10 A. Ensure the operating case temperature remains within limits to maintain the 10 A rating. Verify that the 45 V reverse voltage rating exceeds the maximum circuit voltage. Consider thermal resistance values for heatsink sizing in high-power environments.

Diode Arrays Part Context

This part belongs to the Vishay MBR10xx family of Schottky Barrier Rectifiers, which includes variants like MBRF10xx and MBRB10xx offering different package options such as ITO-220AC and D2PAK. The series is designed for general-purpose rectification with high surge capability and is available in both commercial and automotive qualified versions.

Diode Arrays Replacement Considerations

Direct substitutes include other Vishay parts within the same series, such as MBR1045-E3/45 or MBR1045-M3/45, which share identical electrical ratings but may differ in halogen-free status or packaging revisions. Cross-brand replacements must match the 10 A current, 45 V voltage, and TO-220AC package constraints.
