TBC847B

TOSHIBA · Bipolar (BJT) · SOT-23

TBC847B from TOSHIBA, 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 passive Base terminal of the NPN transistor; the absolute maximum ratings table includes a base current (IB) rating for this terminal.
2 Emitter passive Emitter terminal of the NPN transistor; the emitter-base voltage (VEBO) absolute maximum rating applies between this terminal and the base.
3 Collector passive Collector terminal of the NPN transistor; the collector-base (VCBO) and collector-emitter (VCEO) absolute maximum ratings apply to this terminal.
