Diode Arrays Procurement Notes

Verify that the ordering suffix HE3 confirms RoHS compliance and AEC-Q101 qualification status. Confirm the package type matches the required ITO-220AB form factor. Ensure the specific revision code associated with the part number aligns with the intended manufacturing batch requirements.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for space-constrained designs. The ITO-220AB package offers a balance between thermal performance and mounting flexibility. Consider the 45 V rating for low-voltage systems where standard silicon rectifiers would incur excessive conduction losses.

Diode Arrays Part Context

This component belongs to Vishay's MBRF20xxCT series of dual common cathode Schottky rectifiers. The series includes variants with different reverse voltage ratings, such as 60 V options. The HE3 suffix indicates an automotive-grade version compliant with AEC-Q101 standards, distinguishing it from commercial grade E3 or halogen-free M3 variants.
