Procurement Notes

Verify the supply status carefully as this part may be marked as Not Recommended for New Designs (NRND). Confirm that the specific suffix HT116 matches the required reel packaging quantity and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT-23-3 package before finalizing procurement decisions.

Selection Notes

Select this component when a dual switching diode with high voltage tolerance and automotive qualification is required. The 100 V peak reverse voltage provides robust protection against transient spikes. Consider the 4 ns recovery time for high-frequency applications. Verify that the 250 mW power dissipation rating meets the thermal requirements of the target application environment.

Part Context

This component belongs to the ROHM BAV99 series of small signal switching diodes. It shares the same functional characteristics as other variants in the family but is distinguished by its specific packaging and automotive qualification. The series is designed for general-purpose switching tasks where speed and reliability are critical factors in circuit performance.
