2SA1182-Y

TOSHIBA · Bipolar (BJT) · TO-236-3(SOT-23-3)

2SA1182-Y from TOSHIBA, in a TO-236-3(SOT-23-3). 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 input Base of the PNP transistor; the datasheet limits emitter-base voltage VEBO to -5 V and base current IB to -50 mA.
2 EMITTER passive Emitter of the PNP transistor; the datasheet limits VEBO to -5 V.
3 COLLECTOR passive Collector of the PNP transistor; the datasheet gives VCBO of -35 V, VCEO of -30 V and IC of -500 mA.
