2SD2114KT146V

ROHM Semicon · Bipolar (BJT) · TO-236-3(SOT-23-3)

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).
