Single Diodes Procurement Notes

Verify the specific suffix 'T116' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the component meets the AEC-Q101 qualification requirements for your specific automotive application environment. Ensure the ordering part number matches the exact RoHS compliance status indicated in the official datasheet before finalizing procurement documentation.

Single Diodes Selection Notes

Select this component when designing for space-constrained automotive PCB layouts requiring a single Schottky diode configuration. It is suitable for applications demanding low forward voltage drop and high thermal stability up to 150 °C. Consider the 30 V reverse voltage rating and 0.2 A current capacity to ensure adequate margin for the target circuit conditions.

Single Diodes Part Context

This component belongs to ROHM's series of automotive Schottky barrier diodes designed for high reliability in vehicle electronics. It utilizes silicon technology and is housed in the widely adopted SOT-23 package. The product line emphasizes miniaturization and robust performance under automotive operating conditions, distinguishing it from general-purpose industrial diodes through its specific qualification standards.

Single Diodes Replacement Considerations

BAT54SHYFHT116: Same pinout and package; verify if dual-anode common-cathode configuration is acceptable instead of single.
