2SA733

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92

2SA733 from Foshan Blue Rocket Elec, 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 Base passive Base terminal of the PNP transistor; the datasheet limits continuous base current to -20 mA (IB) and emitter-to-base voltage to -5.0 V (VEBO).
2 Collector passive Collector terminal of the PNP transistor; the datasheet limits collector-to-base voltage to -60 V (VCBO), collector-to-emitter voltage to -50 V (VCEO), continuous collector current to -150 mA (IC), and collector power dissipation to 250 mW (PC).
3 Emitter passive Emitter terminal of the PNP transistor; the datasheet limits emitter-to-base voltage to -5.0 V (VEBO) with respect to the base.
