Applications

General RF amplifier circuits

Procurement Notes

Verify the specific ordering suffix required for plating options. The BK suffix indicates stock-only availability as part of an End of Life notice. Confirm if PBFREE or TIN/LEAD suffixes are needed for compliance. Contact [email protected] for alternate sourcing assistance if standard supply is unavailable.

Selection Notes

Select this component for low-power RF amplification tasks requiring a compact SOT-23 footprint. Ensure the design accommodates the 20 V voltage limits and 50 mA current constraints. Verify thermal management requirements against the 225 mW dissipation limit on the target PCB substrate.

Part Context

This component belongs to the Central Semiconductor discrete transistor portfolio, specifically categorized as a surface-mount PNP silicon RF device. It utilizes the standard SOT-23 mechanical outline and is marked with code C3D or 3D for identification.

Replacement Considerations

No direct replacement part numbers are available from the manufacturer. The BK variant is classified as End of Life with stock-only availability. Consult the manufacturer's engineering team for potential alternate sources.
