# UCLAMP1211P

**TECH PUBLIC** · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

UCLAMP1211P from TECH PUBLIC, in a DFN1006-2. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Pin 1 (TVS terminal) | passive | One of the two terminals of the bidirectional TVS clamp, rated for a nominal reverse working voltage of 12 V max and a clamping voltage of 12 V max at 8 A (8/20 µs). |
| 2 | Pin 2 (TVS terminal) | passive | The other terminal of the bidirectional TVS clamp; the device is symmetric, so either terminal can be the protected line, with reverse leakage of 100 nA max at 12 V. |
