2N5551
by CJ(江苏长电/长晶)The CJ 2N5551 is a high-voltage NPN bipolar transistor for discrete amplifier stages and switching circuits. This library conversion has already been used by 2 ProtoFlow engineers in real designs. The through-hole TO-92-3 format accommodates leaded component layouts, with base, collector, and emitter connections represented in the schematic symbol. For schematic capture, the free KiCad download provides that 3-pin symbol; for PCB layout, it supplies the TO-92-3_L4.9-W3.7-P2.54-L footprint with 3 pads. A 3D model is included to show the transistor body in the board view. The 2N5551 library entry can be opened directly in ProtoFlow.
