DDTA114ECA-7-F from Diodes Incorporated, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | input | Base input through the 10kΩ R1 series resistor; the rated input voltage (pin 1 to pin 2) for DDTA114ECA is +10 to -40 V. |
| 2 | GND (+) | power_in | Common ground/positive reference (emitter) of the PNP pre-biased transistor, against which VIN and VCC are rated. |
| 3 | OUT | output | Collector output; supply voltage VCC (pin 3 to pin 2) is rated -50 V and output current IO is rated -50 mA for DDTA114ECA. |

CAD (land: KiCad; 3D: generated from the datasheet)
- Symbol:
DDTA114ECA-7-F - Footprint:
Package_TO_SOT_SMD:SOT-23 - 3D model: SOT-23, generated on the KiCad land (body 1.3 x 2.9 mm, terminals on the pads, 1.025 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
