DTC143ZUA-TP

MCC(Micro Commercial Components) · Digital Transistors · SOT-323

DTC143ZUA-TP from MCC(Micro Commercial Components), in a SOT-323. 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 IN input Base input of the transistor, with built-in biasing resistor R1 (4.7 kΩ typ.); input voltage is rated from -5 V to 30 V, with VI(off) min 0.5 V and VI(on) max 1.3 V.
2 GND power_in Ground reference pin (marked GND(+) in the internal structure diagram), with the emitter connected to this pin through the built-in network.
3 OUT output Collector output of the transistor; the datasheet rates collector current at 100 mA, with VO(on) max 0.3 V at IO=5 mA and IO(off) max 0.5 µA.
