2SC2073

JSMSEMI · Bipolar (BJT) · TO-220

2SC2073 from JSMSEMI, in a TO-220. 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 terminal of the NPN transistor; the datasheet gives a continuous base current rating of 0.5 A.
2 Collector passive Collector terminal of the NPN transistor; the datasheet gives a collector-to-base voltage of 150 V, a continuous collector current of 1.5 A, and a collector power dissipation of 25 W at Tc=25°C.
3 Emitter passive Emitter terminal of the NPN transistor; the datasheet gives an emitter-to-base voltage rating of 5.0 V.
