DTC144ECAT116

ROHM Semicon · Digital Transistors · SOT-23

DTC144ECAT116 from ROHM Semicon, in a SOT-23. 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, connected to the R2 bias resistor (R2 = 47kΩ).
2 IN (BASE) input Base input through built-in R1 = 47kΩ, with VI(off) max 0.5V, VI(on) min 3.0V and input voltage range -10 to 40V.
3 OUT (COLLECTOR) output Open-collector output of the NPN transistor, rated for supply voltage VCC 50V, output current IO 30mA and IC(MAX) 100mA.
