# TVS1800DRVR

**Texas Instruments** · Surge Protection Devices (SPDs) · WSON-6(2x2)

TVS1800DRVR from Texas Instruments, in a WSON-6(2x2). 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. |
