DTA113ZCAT116

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

DTA113ZCAT116 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, used as the GND (+) terminal and connected to R2; the device is rated for VCC of -50V.
2 IN (BASE) input Base input through built-in R1 (1kΩ), with input voltage rated -10 to 5 V and VI(off) max -0.3 V and VI(on) min -3.0 V.
3 OUT (COLLECTOR) output Collector output of the built-in transistor, rated for output current of -100 mA and supply voltage of -50 V.
