Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | input | Input pin - connects to base through built-in R1 = 47kΩ series resistor (with R2 = 10kΩ from base to emitter). Drives the PNP transistor's base for switching. VIN rating +15 to -40V; VI(off) ≥ -1.0V; VI(on) typ -5.0V; input current at VI = -5V typ -0.16mA. |+| 2 | GND | passive | Ground / emitter (+) terminal of the PNP pre-biased transistor. For PNP digital transistors this is the positive supply reference (labeled GND(+) in the datasheet). |+| 3 | OUT | output | Output pin - collector of the PNP transistor. Open-collector style output. Supply/output voltage rating VCC = -50V (pin 3 to pin 2); IO max = -30mA; IO(off) ≤ -0.5µA at VCC = -50V, VI = 0V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-323 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `DDTA144VUA-7-F`++## CAD (KiCad official)++- Symbol: `DDTA144VUA-7-F`+- Footprint: `Package_TO_SOT_SMD:SOT-323_SC-70`+- 3D model: SOT-323 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603297501336387584) (None pp, sha256 `d7af473cdacc488b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
