2SC2411KT146Q

ROHM Semicon · Bipolar Transistors - BJT · TO-236-3(SOT-23-3)

2SC2411KT146Q from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 E passive Emitter terminal of the NPN transistor; the emitter-base breakdown voltage BVEBO is 5V minimum at IE = 100μA.
2 B passive Base terminal of the NPN transistor; the base current is 50mA at IC = 500mA for saturation (VCE(sat) max 600mV).
3 C passive Collector terminal of the NPN transistor; VCEO is 32V and the maximum collector current IC is 500mA.
