DTC614TKT146

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

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.
