DTC114EKAT146 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 | GND (EMITTER) | power_in | Ground / emitter of the built-in NPN transistor, also the return for the R2 = 10kΩ base-emitter resistor. |
| 2 | IN (BASE) | input | Input (base) through built-in R1 = 10kΩ; input voltage range -10 to 40 V, VI(off) max 0.5 V and VI(on) min 3.0 V. |
| 3 | OUT (COLLECTOR) | output | Output (collector) of the digital transistor; VCC max 50 V, output current IO max 50 mA (IC(MAX) 100 mA). |
