AD-DTA123YM
Changjing · Digital Transistors · SOT-723
AD-DTA123YM from Changjing, in a SOT-723. 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 of the PNP digital transistor, connected through built-in resistor R1 (2.2 kΩ typ) to the base; input voltage range -12 V to +5 V. |
| 2 | GND | power_in | Ground/emitter reference (GND(+)) of the PNP digital transistor, shared with the R2 bias resistor. |
| 3 | OUT | output | Output (collector) of the digital transistor, rated for output current up to -100 mA and supply voltage up to -50 V. |
