ROHM Semicon · Digital Transistors · TO-236-3(SOT-23-3)

DTC114YKAT146 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 terminal of the built-in NPN transistor, connected to the R2 bias resistor (R2 = 47kΩ, ratio R2/R1 3.7 to 5.7).
2 IN (BASE) input Input/base terminal through built-in R1 = 10kΩ (7 to 13kΩ); VI(off) max 0.3V, VI(on) min 1.4V, input voltage rating -6 to 40V.
3 OUT (COLLECTOR) output Output/collector terminal; VCC max 50V, output current IO max 70mA, IC(MAX) 100mA, VO(on) max 300mV at IO = 5mA.
