Single Diodes Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to ensure the correct tape-and-reel packaging format matches production requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents prior to finalizing procurement specifications.

Single Diodes Selection Notes

Select this component when a small-footprint Schottky diode is required for low-voltage, low-current rectification tasks. The 40 V reverse voltage rating provides adequate margin for standard 5 V logic or power rails. Ensure the PCB layout accommodates the SOT-323FL-3 thermal dissipation capabilities given the 100 mA continuous current limit.

Single Diodes Part Context

This part belongs to the RB451 series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by its use in general-purpose rectification where size and switching speed are critical factors. The UMTL suffix typically denotes the specific taping and reel configuration used for surface-mount manufacturing processes.

Single Diodes Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in the provided source material. Verify compatibility with alternative Schottky diodes having matching 40 V reverse voltage, 100 mA forward current, and SOT-323FL-3 package dimensions before substitution.
