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. |
