Diode Arrays Procurement Notes

Verify the specific suffix HE3 confirms AEC-Q101 automotive qualification status. Confirm the E3 suffix indicates RoHS compliance. Ensure the ordering code matches the required TO-220AB package configuration. Validate that the 45V rating aligns with the circuit's maximum reverse voltage requirements before procurement.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or polarity protection. The TO-220AB package facilitates heatsinking for high current loads up to 15 A per diode. Consider the low leakage current and high surge capability for demanding switching environments requiring reliable high-temperature performance.

Diode Arrays Part Context

This part belongs to the MBR25HxxCT series of dual Schottky barrier rectifiers. The series includes variants with different voltage ratings such as 35 V, 50 V, and 60 V. The HE3 designation specifically denotes AEC-Q101 qualification, distinguishing it from the commercial grade E3 versions within the same physical package family.

Diode Arrays Replacement Considerations

Direct substitutes within the same Vishay series include MBR25H35CTHE3/45, MBR25H50CTHE3/45, and MBR25H60CTHE3/45. These parts share identical pinouts and thermal characteristics but differ in maximum reverse voltage ratings. Verify voltage compatibility before substitution.
