DTC143ZUAT106

ROHM Semicon · Digital Transistors · SOT-323(SC-70)

DTC143ZUAT106 from ROHM Semicon, in a SOT-323(SC-70). 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; R2 (47kΩ) connects between this pin and the input base node.
2 IN (BASE) input Input / base connected through built-in R1 = 4.7kΩ, with input voltage VI(off) max 0.5V, VI(on) min 1.3V and absolute maximum VIN of -5 to 30V.
3 OUT (COLLECTOR) output Output / collector of the built-in NPN transistor, rated for VCC 50V and IO 100mA maximum.
