2SD2114KT146V from ROHM Semicon, in a TO-236-3(SOT-23-3). 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 terminal of the NPN transistor; the datasheet gives a minimum emitter-base voltage VEBO of 12 V. |
| 2 | Base | passive | Base terminal; the datasheet gives a typical VCE(sat) of 0.18 V at IC/IB = 500 mA/20 mA. |
| 3 | Collector | passive | Collector terminal; absolute maximum ratings are VCBO 25 V, VCEO 20 V and DC collector current IC 0.5 A (1 A pulse, single pulse Pw = 100 ms). |
