Changjing · Bipolar (BJT) · SOT-323

2SC4116 from Changjing, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base of the NPN transistor; V(BR)EBO is 5 V min (IE=100μA) and IEBO is 0.1 μA max at VEB=5V.
2 EMITTER passive Emitter of the NPN transistor; maximum emitter-base voltage VEBO is 5 V.
3 COLLECTOR passive Collector of the NPN transistor; VCBO is 60 V, VCEO is 50 V and maximum collector current IC is 150 mA.
