# PESD15VS2UT

**Nexperia** · ESD And Surge Protection (TVS/ESD) · SOT-23

PESD15VS2UT from Nexperia, in a SOT-23. 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 | K1 | passive | Cathode of diode 1; the line to be protected connects here, and the diode is measured from pin 1 to pin 3 (common anode). |
| 2 | K2 | passive | Cathode of diode 2; the second line to be protected connects here, and the diode is measured from pin 2 to pin 3 (common anode). |
| 3 | A | passive | Common anode shared by both ESD protection diodes, typically connected to ground. |

## CAD (KiCad official)

- Symbol: `PESD15VS2UT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `pesd15vs2ut-etched.step` / `pesd15vs2ut-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesd15vs2ut.step` / `pesd15vs2ut.glb` are the bare package body.
