DTC143ZCAT116

ROHM Semicon · Digital Transistors · SOT-23

DTC143ZCAT116 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, also connected to the end of R2 (R2 = 47kΩ typ.).
2 IN (BASE) input Input / base through built-in R1 (4.7kΩ typ.); VI(off) max 0.5V, VI(on) min 1.3V, input voltage rating -5 to 30V.
3 OUT (COLLECTOR) output Output / collector of the built-in NPN transistor; supply voltage VCC 50V max and output current 100mA max.
