2SC1815-MS

MSKSEMI · Bipolar (BJT) · SOT-23

2SC1815-MS from MSKSEMI, 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 datasheet gives VEBO of 5 V and the emitter-base breakdown voltage V(BR)EBO of 5 V min at IE = 100 uA.
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet gives a maximum emitter-base voltage VEBO of 5 V and a maximum collector current IC of 150 mA.
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet gives VCBO of 60 V, VCEO of 50 V and a collector current IC of 150 mA, with PC of 200 mW.
