2SC2873

hongjiacheng · Bipolar (BJT) · SOT-89

2SC2873 from hongjiacheng, in a SOT-89. 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 B input Base terminal; the datasheet gives hFE 70 to 240 at IC=500mA and VCE=2V, and VBE(sat) of 1.2V max at IC=1A and IB=50mA.
2 C passive Collector terminal; rated for VCBO 50V, VCEO 50V, IC 2.0A, and 500mW collector power dissipation.
3 E passive Emitter terminal; rated for VEBO 5.0V maximum emitter-base voltage.
