DTA143XCA

Changjing · Digital Transistors · SOT-23

DTA143XCA 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	Input pin to the built-in bias network (R1 = 4.7 kΩ typ., 3.29 to 6.11 kΩ); input voltage is rated −20 V to +7 V.
2	GND	power_in	Common ground reference for the device; the datasheet gives no separate electrical limit for this pin.
3	OUT	output	Output pin of the inverter stage, rated for output current up to −100 mA and supply voltage VCC down to −50 V, with on-state output voltage VO(on) of −0.1 to −0.3 V at IO/II = −10 mA/−0.5 mA.
