2SA733L-P-T92-B

UTC Unisonic Tech · Bipolar (BJT) · TO-92

2SA733L-P-T92-B from UTC Unisonic Tech, 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 E passive Emitter of the PNP transistor; in the TO-92 pin assignment for this part it is pin 1, and the datasheet gives the emitter-base voltage limit VEBO of -5 V.
2 C passive Collector of the PNP transistor; the datasheet limits collector-emitter voltage to VCEO -50 V and collector current to -150 mA, with 750 mW TO-92 collector power dissipation at TC=25°C.
3 B passive Base of the PNP transistor; the datasheet gives the base-drive test condition IB=-10 mA for IC=-100 mA saturation voltage measurement.
