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 | GND | passive | Ground / cathode return of the TVS clamp. Pins 1, 2, 3 and the exposed thermal pad are all internally tied to GND and should connect together to the system ground plane for lowest inductance and best thermal dissipation. |+| 2 | GND | passive | Ground / cathode return of the TVS clamp. Tie to GND together with pins 1, 3 and the exposed thermal pad. |+| 3 | GND | passive | Ground / cathode return of the TVS clamp. Tie to GND together with pins 1, 2 and the exposed thermal pad. |+| 4 | IN | passive | ESD and surge protected channel (anode of the TVS clamp). 18V reverse standoff voltage, clamps at ~22.8V at Ipp (40A, 8/20us). Pins 4, 5, 6 are internally connected and should be tied together at the protected signal/rail line. |+| 5 | IN | passive | ESD and surge protected channel. Internally tied to pins 4 and 6; connect all three to the protected line for lowest series impedance. |+| 6 | IN | passive | ESD and surge protected channel. Internally tied to pins 4 and 5; connect all three to the protected line for lowest series impedance. |+| EP | GND | passive | Exposed thermal pad on the bottom of the SON-6 package. Internally connected to GND (pins 1, 2, 3); must be soldered to the ground plane for proper thermal performance and mechanical retention. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | WSON-6(2x2) |+| Category | Circuit Protection |+| Pins | 7 |++## Ordering variants++Same part, different packaging or reel option.++- `TVS1800DRVR`+- `TVS1800DRVRDRVT`++## CAD (KiCad official)++- Symbol: `TVS1800DRVR`+- Footprint: `Package_SON:WSON-6-1EP_2x2mm_P0.65mm_EP1x1.6mm`+- 3D model: WSON-6(2x2) (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tvs1800) (22 pp, sha256 `bc51ca208dafd0ba`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
