DTA144EE from Yangzhou Yangjie Elec Tech, in a SOT-523. 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 through built-in R1 (32.9 to 61.1 kΩ, 47 kΩ typ) to the base; input voltage rated -40 V to 10 V. |
| 2 | GND | power_in | Ground/emitter reference, labelled GND(+) in the equivalent circuit, where R2 returns to the emitter. |
| 3 | OUT | output | Output (collector) of the PNP digital transistor; output current rated -100 mA and supply voltage -50 V maximum. |
