DTA143XUA
Yangzhou Yangjie Elec Tech · Digital Transistors · SOT-323
DTA143XUA from Yangzhou Yangjie Elec Tech, 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 | Input via built-in series resistor R1 (typ. 4.7 kΩ) to the PNP base; input voltage rated -20 V to +7 V. |
| 2 | GND | power_in | Ground/common (GND(+)) connected to the emitter and R2 of the PNP digital transistor. |
| 3 | OUT | output | Output (collector) of the PNP transistor, rated for output current of -100 mA and supply voltage of -50 V. |
