Diode Arrays Procurement Notes

Verify that the ordering suffix matches the required compliance specifications. The standard BP designation indicates lead-free finish and RoHS compliance. Confirm the halogen-free status if the HF suffix is required. Ensure the package type corresponds to the ITO-220AB physical dimensions provided in the datasheet before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component for circuits requiring a 45V blocking voltage and 30A continuous current handling capability. The ITO-220AB package provides a thermal resistance of 5°C/W from junction to case, which facilitates heat dissipation in high-power environments. Verify that the operating junction temperature range of -65°C to +150°C aligns with the specific environmental conditions of the target application design.

Diode Arrays Part Context

This part belongs to the MBR3020FCT through MBR30100FCT series manufactured by Micro Commercial Components. The series covers voltage ratings from 20V to 100V while maintaining a consistent 30 Amp current capacity across all variants. The MBR3045FCT specifically addresses applications requiring a 45V reverse voltage rating within this standardized product family.

Diode Arrays Replacement Considerations

Cross-reference other manufacturers offering 30A 45V Schottky rectifiers in the ITO-220AB package. Verify that substitute parts meet or exceed the 250A surge current rating and the 0.85V forward voltage specification at 15A to ensure equivalent circuit performance.
