ADTC124ECAQ-7

Diodes Incorporated · Digital Transistors · SOT-23

ADTC124ECAQ-7 from Diodes Incorporated, 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 IN input Input (base side with built-in R1 22kΩ), input voltage referenced to pin 2 rated -10 to +40 V, with Vl(OFF) 0.5 V min and Vl(ON) 3 V max.
2 GND power_in Ground (emitter), the 0 V reference for the input voltage (pin 1 to 2) and supply voltage (pin 3 to 2).
3 OUT output Output (collector), supply voltage VCC rated 50 V to pin 2, output current IO 30 mA and IC (max) 100 mA.
