Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix matches the required hFE binning group and packaging format. Confirm that the SOT323 package variant aligns with the design's thermal and spatial constraints. Ensure compliance with the stated environmental directives before finalizing procurement specifications.

Single Bipolar Transistors Selection Notes

Select this component when a low-voltage NPN transistor with moderate power handling is required. The SOT323 package offers a compact footprint suitable for space-constrained designs. Verify that the hFE group 25 range satisfies the circuit's gain requirements without necessitating additional trimming or selection processes.

Single Bipolar Transistors Part Context

This part belongs to the BC817K/BC818K family of NPN/PNP silicon transistors intended for audio frequency use. The 'W' designation indicates the SOT323 surface-mount package. The 'E6433' suffix typically denotes specific tape-and-reel packaging configurations used by distributors.

Single Bipolar Transistors Replacement Considerations

Direct substitutes within the same family include BC 817K-16W and BC 817K-40W, which share identical pinouts and packages but differ in hFE gain ranges and breakdown voltages respectively.
