2222A

MOT · Bipolar (BJT) · SOT-23

2222A from MOT, in a SOT-23. 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	passive	Base terminal of the NPN transistor; the datasheet gives no pin-specific limit, only the absolute maximum ratings for the device (VEBO 6 V, IC 600 mA continuous).
2	Emitter	passive	Emitter terminal of the NPN transistor, with the emitter-base voltage limited to 6 V (VEBO) by the maximum ratings.
3	Collector	passive	Collector terminal of the NPN transistor, rated for 75 V collector-base (VCBO), 40 V collector-emitter (VCEO), and 600 mA continuous collector current (IC).
