Procurement Notes
Verify the specific ordering suffix matches the required packing type, such as 3K pcs on a 7-inch reel or 12K pcs on a 13-inch reel. Confirm that the device marking corresponds to '8B' for the BC817-25 variant. Ensure compliance with RoHS 2011/65/EU directives and halogen-free requirements during component qualification.
Selection Notes
Select this component when a 45 V collector-emitter breakdown voltage and 500 mA continuous current capability are required. The BC817-25 variant offers a DC current gain range of 160 to 400, suitable for moderate amplification needs. Consider the SOT-23 package dimensions and thermal resistance characteristics for PCB layout and heat dissipation planning.
Part Context
