DTA123EKAT146

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

DTA123EKAT146 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 (positive reference) of the PNP digital transistor, with R2 connected between it and the input (base) node.
2 IN (BASE) input Input (base) terminal through built-in R1 of 2.2kΩ, with VI(off) max -0.5V, VI(on) min -3.0V and an absolute maximum input voltage of -12 to 10V.
3 OUT (COLLECTOR) output Output (collector) terminal, rated for output current IO of -100mA and supply voltage VCC of -50V maximum.
