2SA2222SG

onsemi · Bipolar (BJT) · TO-220F-3

2SA2222SG from onsemi, in a TO-220F-3. 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; the datasheet limits base current IB to -2 A and emitter-to-base voltage VEBO to -6 V (absolute maximum ratings).
2 Collector passive Collector terminal; the datasheet limits collector-to-emitter voltage VCEO to -50 V, collector current IC to -10 A (pulse ICP -13 A), and collector dissipation PC to 25 W at Tc=25°C.
3 Emitter passive Emitter terminal; it is the reference for the collector-to-emitter (VCEO -50 V) and emitter-to-base (VEBO -6 V) ratings.
