2SC945M-P

Foshan Blue Rocket Elec · Bipolar (BJT) · SOT-23

2SC945M-P from Foshan Blue Rocket Elec, 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, with a continuous base current rating IB of 20 mA.
2 Emitter passive Emitter terminal of the NPN transistor, with an emitter-to-base voltage rating VEBO of 5.0 V.
3 Collector passive Collector terminal of the NPN transistor, rated for 50 V collector-to-emitter (VCEO), 150 mA continuous collector current (IC) and 250 mW collector power dissipation (PC).
