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. |
