Diode Arrays Procurement Notes

Verify that the ordering suffix 'H' confirms AEC-Q101 qualification as specified by the manufacturer. Ensure the component matches the ITO-220AB package outline and marking diagram requirements. Confirm RoHS compliance and halogen-free status according to IEC 61249-2-21 before integration into designs requiring specific environmental certifications.

Diode Arrays Selection Notes

Select this component for applications requiring a 90 V reverse voltage rating and 15 A continuous current handling. The ITO-220AB flange mount package facilitates effective thermal management via the isolated cathode tab. Consider the 0.92 V maximum forward voltage drop for efficiency calculations in low-voltage, high-frequency circuits where switching losses are critical.

Diode Arrays Part Context

This part belongs to the MBRF15xCT series, which covers voltage ratings from 35 V to 150 V. All variants share identical mechanical dimensions and thermal characteristics within the ITO-220AB form factor. The 'H' suffix specifically denotes AEC-Q101 qualification, distinguishing it from standard industrial grade versions while maintaining identical electrical performance parameters.

Diode Arrays Replacement Considerations

Cross-reference with other manufacturers offering 15 A, 90 V Schottky rectifiers in the ITO-220AB package. Verify pinout compatibility and thermal resistance values when substituting. Ensure the replacement meets the same AEC-Q101 qualification if automotive reliability is required.

Diode Arrays FAQ
