Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm the exact reel quantity and manufacturing origin. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement specifications.
Selection Notes
Select this component when a small SMD footprint is required alongside high DC current gain. Ensure the design accommodates the 200 mW power dissipation limit and verify that the 45 V collector-emitter voltage rating meets the circuit requirements.
Part Context
This part belongs to the BC850W series of NPN general-purpose transistors. It serves as the complement to the BC849W series. The BC850CW variant specifically denotes a tight binning range for DC current gain, distinguishing it from other gain grades within the same package family.
