Procurement Notes
Verify the specific ordering suffix matches the required reel size and tape width configuration. Confirm that the component meets all applicable environmental compliance requirements for the target assembly process. Ensure the manufacturer's datasheet revision aligns with the design specifications before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN transistor with moderate current handling capabilities is required. The SOT323 package is suitable for space-constrained designs. Consider the hFE range of 160 to 400 for biasing calculations in amplifier applications. Verify thermal management needs against the 200 mW power dissipation limit.
Part Context
This part belongs to the BC817-xxW series of general-purpose NPN transistors. It is designed as a complement to the BC807-xxW PNP types. The series is optimized for automatic insertion into printed circuit boards. The 'W' designation indicates the SOT323 package format.
Replacement Considerations
Compatible substitutes include BC817-25W-7-F from Nexperia and BC817-25W-7 from other manufacturers offering identical electrical parameters and SOT323 packaging. Verify pinout compatibility and thermal resistance values before substitution.
