2SC2120-Y

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92

2SC2120-Y from Foshan Blue Rocket Elec, in a TO-92. 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; the datasheet gives no separate pin-specific limit, and the emitter-to-base rating is VEBO 5.0 V.
2 Collector passive Collector of the NPN transistor, rated VCBO 35 V, VCEO 30 V, IC 800 mA continuous and PC 600 mW.
3 E passive Emitter of the NPN transistor, rated IE -800 mA continuous (magnitude 800 mA) with VEBO 5.0 V.
