# PESD5V0U2BT

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

PESD5V0U2BT 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, one of the two bidirectional ESD-protected signal lines (line 1), sharing the common cathode CC. |
| 2 | K2 | passive | Cathode of diode 2, the second bidirectional ESD-protected signal line (line 2), sharing the common cathode CC. |
| 3 | CC | passive | Common cathode that ties the cathodes of diode 1 and diode 2 together; the datasheet gives no separate electrical limit for this pin. |

## CAD (KiCad official)

- Symbol: `PESD5V0U2BT`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `pesd5v0u2bt-etched.step` / `pesd5v0u2bt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesd5v0u2bt.step` / `pesd5v0u2bt.glb` are the bare package body.
