Procurement Notes

Verify the specific ordering suffix FT to ensure tape-and-reel packaging configuration matches assembly requirements. Confirm that the 12 V peak reverse voltage rating aligns with the system's maximum bias conditions. Check datasheet specifications for thermal management needs within the SOT-23 package constraints. Ensure compatibility with lead-free manufacturing processes as indicated by RoHS documentation.

Selection Notes

Select this component when limited supply voltage requires efficient tuning across a broad frequency range. The hyperabrupt profile provides superior linearity compared to abrupt junction types. Consider the 2.85 pF base capacitance for impedance matching networks. Evaluate the 50 mA current handling capability against circuit drive levels. Verify that the SOT-23 footprint fits the available PCB real estate.
