DTC614TKT146 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 of the NPN digital transistor with built-in 10kΩ (7 to 13kΩ) base resistor; emitter-base voltage limit VEBO is 12V. |
| 2 | Base | input | Base input connected through the built-in R1 = 10kΩ (typ.) series resistor; drives up to IC = 600mA collector current. |
| 3 | Collector | passive | Collector of the NPN digital transistor with VCEO of 20V, VCBO of 20V and maximum collector current of 600mA. |
