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 | Base input through built-in series resistor R1 (2.2 kΩ nom). Input voltage range -10 V to +12 V. Drives the NPN base via R1 with R2 (2.2 kΩ) shunting base-to-emitter for defined off-state. |+| 2 | GND | passive | Emitter / common ground reference (labeled GND(0) on the device schematic). Return for both the input bias network (R2) and the output collector current. |+| 3 | OUT | output | Open-collector output. Absolute max VCC (pin 3 to pin 2) = 50 V; max output/collector current IC = 100 mA. Pulls low toward VO(on) ≈ 0.1 V (max 0.3 V) when input is asserted. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-23-3 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `DDTC123ECAQ-7-F`++## CAD (KiCad official)++- Symbol: `DDTC123ECAQ-7-F`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8603156795083014144) (None pp, sha256 `b71e1c1af45adb44`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
