2SA733G-P-AE3-R

UTC Unisonic Tech · Bipolar (BJT) · SOT-23

2SA733G-P-AE3-R from UTC Unisonic Tech, 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 B passive Base terminal of the PNP transistor; the absolute maximum emitter-base voltage VEBO is -5 V, and IEBO is specified at VEB=-3V.
2 E passive Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage VEBO is -5 V.
3 C passive Collector terminal of the PNP transistor; rated for a collector-emitter voltage VCEO of -50 V and a collector current up to -150 mA.
