KTC9018S-H-RTK

KEC Semicon · Bipolar (BJT) · SOT-23

KTC9018S-H-RTK from KEC Semicon, 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 EMITTER passive Emitter terminal of the NPN transistor; the datasheet rates emitter current IE at -20 mA (absolute maximum).
2 BASE passive Base terminal of the NPN transistor; the datasheet rates emitter-base voltage VEBO at 4 V maximum.
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet rates collector current IC at 20 mA, collector-base voltage VCBO at 40 V and collector-emitter voltage VCEO at 30 V (maximum ratings).
