2SA733M-P

Foshan Blue Rocket Elec · Bipolar (BJT) · SOT-23

2SA733M-P from Foshan Blue Rocket Elec, 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	input	Base terminal of the PNP transistor, with base current IB limited to -20 mA in the absolute maximum ratings.
2	Emitter	passive	Emitter terminal of the PNP transistor, with emitter-to-base voltage VEBO limited to -5.0 V in the absolute maximum ratings.
3	Collector	passive	Collector terminal of the PNP transistor, with collector current IC limited to -150 mA, collector-to-emitter voltage VCEO to -50 V and collector power dissipation PC to 200 mW.
