Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part matches the specific BC818K16 variant requirements. Check datasheet revisions for any updates regarding electrical characteristics or packaging changes. Ensure compliance with RoHS directives if required by your manufacturing process.

Selection Notes

Select this component when a 25 V NPN transistor with a guaranteed minimum hFE of 100 is needed. It suits designs prioritizing low saturation voltage for efficient switching. Consider the SOT-323 footprint constraints during layout planning. Evaluate thermal management needs based on the 250 mW power dissipation limit in the specified package.

Part Context

This part belongs to the BC818K family of NPN silicon transistors intended for audio frequency use. It shares pin configurations and mechanical dimensions with related variants like the BC817K series, differing primarily in breakdown voltage ratings. The '16' suffix denotes the specific DC current gain grouping.

Replacement Considerations

Direct substitutes include other BC818K variants with matching gain groups. Cross-reference with BC817K parts only if voltage ratings align with circuit requirements. Verify package compatibility before substitution.
