Procurement Notes
Verify the specific hFE binning group required for your design, as the '16' suffix indicates a gain range of 100 to 250. Confirm that the SOT-23 package dimensions match your PCB footprint. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Check for any specific handling instructions regarding thermal resistance during soldering.
Selection Notes
Select this component when a standard NPN BJT with moderate gain and low saturation voltage is needed for audio or switching tasks. The AEC-Q101 qualification makes it suitable for automotive environments. Compare against other hFE groups if higher gain is necessary, or consider the BC818 variant for lower voltage ratings. Ensure the 500 mA continuous current rating aligns with your circuit's peak load requirements.
Part Context
This part belongs to the BC817K series of NPN silicon transistors from Infineon. The series includes variants with different hFE bins (e.g., -25, -40) and packages (SOT-23, SOT-323). The BC817K16 specifically denotes the hFE group 16 configuration. It is part of Infineon's portfolio of general-purpose discrete semiconductors designed for robust performance in various electronic applications.
Replacement Considerations
Direct substitutes within the same family include BC817K25E6433HTMA1 and BC817K40E6433HTMA1, which offer different DC current gain ranges. Ensure the replacement maintains the SOT-23 package and compatible pinout. Verify that the alternative part meets the same AEC-Q101 qualification if used in automotive contexts.
