Diode Arrays Procurement Notes

Verify the specific suffix HE3 indicates AEC-Q101 qualification and RoHS compliance. Confirm the /45 suffix corresponds to the tube packaging format. Ensure the component matches the TO-220AB mechanical dimensions. Validate that the manufacturer source document confirms the exact part number designation before procurement.

Diode Arrays Selection Notes

Select this component when automotive-grade reliability is required for high-frequency rectification applications. The dual common cathode configuration allows for efficient use in bridge or center-tapped topologies. Consider the thermal resistance characteristics for heat sink design. Verify that the 50 V reverse voltage rating aligns with the circuit's peak inverse voltage requirements.

Diode Arrays Part Context

This part belongs to the MBR30HxxCT series, which includes variants with different reverse voltage ratings such as 35 V, 45 V, and 60 V. The series utilizes high barrier Schottky technology to minimize leakage current at elevated temperatures. The HE3 suffix specifically denotes AEC-Q101 qualification, distinguishing it from the commercial grade E3 variant.

Diode Arrays Replacement Considerations

MBR30H50CT-E3/45 serves as the commercial grade equivalent without automotive qualification. Other voltage variants within the same package include MBR30H45CTHE3/45 and MBR30H60CTHE3/45.
