2N3906
by ST(先科)
For small-signal switching and amplification, the 2N3906 is a familiar PNP bipolar transistor. It is commonly used in bias circuits and switching stages where PNP polarity suits the surrounding circuit. This record provides a through-hole implementation with a 3-pin schematic symbol and the TO-92-3_L5.1-W4.1-P1.27-L footprint, which has 3 pads. A 3D model accompanies the free KiCad files, allowing the package to appear in the board assembly view. Use by 1 ProtoFlow engineer in real designs provides practical verification of the conversion. The complete part can be opened directly in ProtoFlow.
