MCC Micro Commercial Components · Bipolar (BJT) · SOT-89

2SC2873-Y-TP from MCC Micro Commercial Components, 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, with DC current gain hFE1 of 70 to 240 at VCE=2V and IC=0.5A and a base-emitter saturation voltage of 1.2 V at IC=1A and IB=50mA.
2 C passive Collector terminal, rated for a collector current IC of 2 A, a collector-base voltage VCBO of 50 V, and a collector-emitter saturation voltage VCE(sat) of 0.5 V at IC=1A and IB=50mA.
3 E passive Emitter terminal, rated for an emitter-base voltage VEBO of 5 V and used as the common reference in the datasheet's common-emitter characteristics.
