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 | IO1 | passive | Protected I/O line 1. Bidirectional TVS diode network to IO2/pin 4; clamps transient voltages above ±24 V VRWM to protect downstream circuitry. Ultra-low 0.8 pF (typ) junction capacitance to GND. |+| 2 | GND | passive | Ground / cathode common return for the TVS array. Connect to the local system ground plane with the shortest possible trace to minimize inductance during ESD events. |+| 3 | GND | passive | Second ground / cathode common return pin for the TVS array. Tied to pin 2 externally on the PCB to a solid GND plane. |+| 4 | IO2 | passive | Protected I/O line 2. Bidirectional TVS diode network to IO1/pin 1; clamps transient voltages above ±24 V VRWM. 0.8 pF (typ) junction capacitance keeps insertion loss low on high-speed lines. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-143 |+| Category | Circuit Protection |+| Pins | 4 |++## CAD (KiCad official)++- Symbol: `LCDA24C-1`+- Footprint: `Package_TO_SOT_SMD:SOT-143`+- 3D model: SOT-143 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TECH PUBLIC datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590922668046557184) (None pp, sha256 `a65b49ac87834099`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
