KTC3198

Foshan Blue Rocket Elec · Bipolar (BJT) · TO-92

KTC3198 from Foshan Blue Rocket Elec, 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 Base input Base terminal of the NPN transistor, with continuous base current limited to 50 mA (IB) and emitter-to-base voltage limited to 5.0 V (VEBO).
2 Collector passive Collector terminal, rated for 60 V collector-to-base (VCBO), 50 V collector-to-emitter (VCEO), 150 mA continuous collector current (IC) and 625 mW collector power dissipation (PC).
3 Emitter passive Emitter terminal of the NPN transistor, rated for emitter-to-base voltage up to 5.0 V (VEBO).
