Diode Arrays Procurement Notes

Verify that the specific ordering suffix matches the required qualification level. The HE3 suffix indicates RoHS compliance and AEC-Q101 qualification, which differs from commercial grade variants. Confirm the package type corresponds to the D2PAK (TO-263AB) form factor. Ensure the delivery mode aligns with tape and reel requirements for automated assembly processes.

Diode Arrays Selection Notes

Select this component when a dual common cathode configuration is required for synchronous rectification or polarity protection. The D2PAK package facilitates efficient thermal dissipation through the heatsink tab. Consider the AEC-Q101 qualification if the application demands automotive-grade reliability. Evaluate the forward voltage characteristics against the specific thermal management constraints of the target circuit design.

Diode Arrays Part Context

This part belongs to the MBRB20xxCT series of dual common cathode Schottky rectifiers. The series includes variants with different reverse voltage ratings, such as 60 V options. The MBRB designation specifically identifies the surface-mount D2PAK package variant, distinguishing it from the through-hole MBRF series housed in ITO-220AB packages.
