Procurement Notes
Verify the specific ordering suffix '-7' corresponds to the 3000-unit reel packaging configuration as documented in the manufacturer's ordering information. Confirm that the 'K6A' marking code matches the required production date codes for your assembly timeline. Ensure compliance with J-STD-020 moisture sensitivity level 1 handling requirements during storage and reflow soldering processes.
Selection Notes
Select this component when a compact SOT323 footprint is required for NPN switching or amplification tasks. The BC817-16W variant provides a guaranteed minimum hFE of 100, suitable for standard logic interfacing. Consider the complementary BC807-16W PNP type if push-pull configurations are needed within the same design family.
Part Context
This part belongs to the BC817-xxW series of 45V NPN small signal transistors produced by Diodes Incorporated. The series includes variants with different current gain ranges, specifically the -16W, -25W, and -40W options. All members share identical electrical ratings and physical dimensions, differing only in their DC current gain specifications.
