Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging configuration. The /81 suffix indicates tape and reel delivery, whereas other suffixes may denote tube packaging. Confirm that the E3 designation aligns with required lead-free and RoHS compliance standards for the target assembly process. Ensure the TO-263AB footprint matches the intended PCB layout constraints.

Diode Arrays Selection Notes

Select this component when a dual common-cathode configuration is required for space-constrained designs. The TO-263AB package offers thermal performance advantages over through-hole alternatives while maintaining comparable current ratings. Consider the 50 V reverse voltage rating relative to the system's peak operating voltages to ensure adequate safety margins. Evaluate the thermal resistance characteristics against the available heatsinking or copper area on the printed circuit board.

Diode Arrays Part Context

This part belongs to the MBR(F,B)15xxCT series from Vishay, which encompasses various voltage ratings ranging from 35 V to 60 V. The series shares identical physical dimensions and pin configurations across different voltage variants, allowing for design flexibility. The MBRB prefix specifically denotes the TO-263AB surface-mount case style, distinguishing it from the through-hole MBR and ITO variants within the same product family.

Diode Arrays Replacement Considerations

Direct replacements within the same Vishay series include MBRB1535CT, MBRB1545CT, and MBRB1560CT, provided the voltage ratings meet the application requirements. Cross-manufacturer equivalents must be verified for matching current ratings, forward voltage characteristics, and package compatibility.
