TIP122
by BLUE ROCKET(蓝箭)
TIP122 from BLUE ROCKET is an NPN Darlington transistor commonly used to switch a load from a control signal. Its through-hole TO-220-3 form makes the three lead positions important when moving from a schematic to a routed board. The KiCad download includes a 3-pin symbol, the 3-pad TO-220-3_L10.0-W4.5-P2.54-L footprint, and a 3D model that helps inspect physical placement. The converted part has been used by 1 ProtoFlow engineer in a real design, checking the import through actual use. Open TIP122 directly in ProtoFlow to review the symbol and footprint.
