Procurement Notes

Verify the specific ordering suffix to confirm tape-and-reel packaging quantities and RoHS compliance status. Ensure the component designation matches the exact manufacturer part number to avoid confusion with similar pinout alternatives. Confirm supply status as this variant may be subject to production lifecycle changes or obsolescence notices from the manufacturer.

Selection Notes

Select this component when a small form factor switching diode with high-speed performance is required. The SOT-323 package offers a balance between thermal dissipation and board space efficiency. Consider the 80V reverse voltage rating and 0.215A continuous current limits to ensure adequate headroom for the target application's electrical demands.

Part Context

This part belongs to ROHM's line of small-signal switching diodes, specifically engineered for general-purpose high-frequency applications. The BAV99 series is widely recognized for its reliability in consumer electronics and industrial control systems. The FMT106 suffix typically denotes the specific taping quantity and packaging format used for automated assembly processes.

Replacement Considerations

The DAN217U is listed as a similar level replacement with the same pinout and package. Verify that the substitute meets the specific reverse voltage and current requirements of the original design before implementation.
