AD-DTA123YCA

Changjing · Digital Transistors · SOT-23

AD-DTA123YCA from Changjing, 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 Base input through built-in resistor R1 (2.2 kΩ typ), with input voltage range -12 V to +5 V, VI(off) min -0.3 V and VI(on) max -3 V.
2 GND power_in Ground (+) terminal connected to the emitter, with supply voltage Vcc rated -50 V.
3 OUT output Collector output with rated output current IO of -100 mA and output-off current IO(off) max -0.5 µA at VCC = -50 V.
