DTA114YUAQ 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 bias resistor R1 (7 to 13 kΩ, typ 10 kΩ) to the transistor base; input voltage rated -40 V to +6 V. |
| 2 | GND | power_in | Ground/emitter reference (GND(+) in the equivalent circuit) shared with R2; the emitter-base voltage rating is -6 V. |
| 3 | OUT | output | Output at the collector of the PNP transistor, rated for collector current of -100 mA and collector-emitter voltage of -50 V. |
