Single Diodes Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm packaging orientation and quantity. The base part number indicates a tube package, while TRL and TRR suffixes denote left or right-oriented tape and reel configurations respectively. Confirm that the selected variant meets the required mechanical mounting constraints for the D2PAK footprint.

Single Diodes Selection Notes

Select this component when a single-anode Schottky rectifier is required for applications demanding low forward voltage drop and high thermal stability. Ensure the circuit operates within the 45 V reverse voltage limit and the 7.5 A average forward current rating. Consider the D2PAK package dimensions and thermal resistance values during PCB layout and heatsinking design to maintain junction temperatures below the 150 °C maximum.

Single Diodes Part Context

This device belongs to the VS-MBRB7... series of high-performance Schottky rectifiers manufactured by Vishay Semiconductors. The series includes variants with different voltage ratings, such as the 35 V rated VS-MBRB735-M3. All members of this family share the same 7.5 A current rating and utilize the same proprietary barrier technology and D2PAK package outline for consistent mechanical integration.

Single Diodes Replacement Considerations

The datasheet lists the VS-MBRB735-M3 as a related product within the same series, offering identical current and package specifications but with a lower 35 V reverse voltage rating. No other direct substitute part numbers are explicitly confirmed in the provided documentation.
