# PESD3V3L2UM

**Nexperia** · ESD And Surge Protection (TVS/ESD) · SOT-883

PESD3V3L2UM from Nexperia, in a SOT-883. 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 | Cathode 1 | passive | Cathode 1 for ESD protection diode with 3.3 V reverse standoff voltage and 3 A peak pulse current rating per 8/20 µs pulse. |
| 2 | Cathode 2 | passive | Cathode 2 for ESD protection diode with 3.3 V reverse standoff voltage and 3 A peak pulse current rating per 8/20 µs pulse. |
| 3 | Common Anode | power_in | Common anode connected to ground as the ESD clamp reference point. |

## CAD (KiCad official)

- Symbol: `PESD3V3L2UM`
- Footprint: `Package_TO_SOT_SMD:SOT-883`
- 3D model: SOT-883, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `pesd3v3l2um-etched.step` / `pesd3v3l2um-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesd3v3l2um.step` / `pesd3v3l2um.glb` are the bare package body.
