# PESD5V0U1BL

**TECH PUBLIC** · ESD Protection Devices · DFN1006-2

PESD5V0U1BL 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 | LINE1 | passive | One terminal of the bidirectional TVS diode that protects one data or power line, with a working peak reverse voltage of 5 V max and a breakdown voltage of 6 V min at 1 mA (datasheet p.2 and p.1 pin diagram; the datasheet does not name this pin). |
| 2 | LINE2 | passive | Other terminal of the bidirectional TVS diode that protects one data or power line, with a reverse leakage current of 200 nA max at VRWM = 5 V and a junction capacitance of 1 pF max at VR = 0 V, f = 1 MHz (datasheet p.2 and p.1 pin diagram; the datasheet does not name this pin). |

## CAD (KiCad official)

- Symbol: `PESD5V0U1BL`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2 (KiCad packages3D, STEP)
- 3D model files: `pesd5v0u1bl-etched.step` / `pesd5v0u1bl-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pesd5v0u1bl.step` / `pesd5v0u1bl.glb` are the bare package body.
