Diode Arrays Procurement Notes

Verify the specific suffix E3/81 against official Vishay documentation to confirm packaging format and RoHS compliance status. Confirm availability as distribution data may vary. Ensure the component matches the required TO-263AB footprint and pinout for your PCB layout. Check for any recent product change notices or end-of-life announcements directly from the manufacturer before finalizing procurement plans.

Diode Arrays Selection Notes

Select this component when a low-loss, high-current Schottky rectifier is needed in a D2PAK package. The 45 V rating suits low-voltage power rails. Compare forward voltage characteristics against alternatives to ensure efficiency targets are met. Verify that the 15 A current handling aligns with the thermal management capabilities of the target application board.

Diode Arrays Part Context

This part belongs to Vishay's MBRB series of Trench MOS Barrier Schottky rectifiers. These devices are designed for general-purpose rectification in medium-power applications. The series offers improved performance over standard Schottky diodes due to lower forward voltage and reduced reverse leakage currents. The MBRB15H45CT variant specifically addresses needs for higher current density in compact surface-mount packages.
