2N2222AU

CBI · Bipolar (BJT) · SOT-89

2N2222AU from CBI, 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 BASE input Base terminal of the NPN transistor, rated with an emitter-base voltage VEBO of 6 V maximum and driven at IB=50 mA for the 500 mA saturation test condition.
2 COLLECTOR passive Collector terminal, rated for a collector-base voltage VCBO of 75 V, a collector-emitter voltage VCEO of 40 V, and a continuous collector current IC of 600 mA.
3 EMITTER passive Emitter terminal, the reference for the 40 V collector-emitter rating and the 6 V emitter-base rating (VEBO) stated for this device.
