Procurement Notes
Verify the specific suffix 'CW' against official Nexperia documentation to confirm the exact hFE binning and packaging type. Ensure the ordering quantity aligns with manufacturer reel specifications. Confirm RoHS compliance status directly with the supplier or through the latest datasheet revision notes prior to final procurement decisions.
Selection Notes
Select this component when a compact PNP transistor with moderate current handling and high gain is required. Compare the 45 V collector-emitter voltage rating against circuit supply levels. Evaluate the 100 mA current limit against load requirements. Consider the SOT-323 thermal characteristics for heat dissipation needs in enclosed designs.
