DTB114EKT146

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

DTB114EKT146 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 Emitter of the built-in PNP transistor, connected to the positive supply side (+) and joined to R2; VCC rating is -50V.
2 IN (BASE) input Base input through built-in R1 = 10kΩ, so no external input resistor is needed; input voltage range is -40 to 10 V.
3 OUT (COLLECTOR) output Collector output of the built-in transistor, rated to a maximum collector current of -500mA.
