MPS2222A from Changjing, in a TO-92. 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 | EMITTER | passive | Emitter terminal of the TO-92 package, which is the reference for the 6 V emitter-base rating (VEBO) and the emitter-base breakdown voltage V(BR)EBO of 6 V. |
| 2 | BASE | passive | Base terminal of the TO-92 package, which is driven during the datasheet tests with IB of 15 mA to 50 mA for saturation and switching characteristics. |
| 3 | COLLECTOR | passive | Collector terminal of the TO-92 package, rated for a continuous collector current of 600 mA with VCEO of 40 V and VCBO of 75 V maximum. |
