KTD1302-AT

KEC Semicon · Bipolar (BJT) · TO-92-3

KTD1302-AT from KEC Semicon, in a TO-92-3. 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 EMITTER passive Emitter of the NPN transistor, with the datasheet rating VEBO of 12 V and collector current IC limited to 300 mA.
2 COLLECTOR passive Collector of the NPN transistor, rated VCBO 25 V, VCEO 20 V, IC 300 mA and PC 625 mW.
3 BASE input Base of the NPN transistor, with base current IB limited to 30 mA.
