2N2222A-338 from ALJ, 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 | NPN emitter terminal, operated within the absolute maximum ratings of VEBO 6 V, IC 600 mA and Tj 150 °C stated for the device. |
| 2 | Base | passive | NPN base terminal, driven in the datasheet's saturation tests at IB = 15 mA for IC = 150 mA and IB = 50 mA for IC = 500 mA. |
| 3 | Collector | passive | NPN collector terminal, limited to VCBO 75 V, VCEO 40 V and IC 600 mA, with collector power dissipation PC of 625 mW maximum. |
