# TPPESD5V0U1UL

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

TPPESD5V0U1UL from TECH PUBLIC, in a DFN1006-2L. 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 | Left terminal of the single-line unidirectional TVS diode, identified by the black band on the package; the datasheet gives Pin 1 to Pin 2 junction capacitance of 0.5 pF typical and 0.7 pF maximum at VR = 0 V, f = 1 MHz. |
| 2 | Pin 2 (TVS terminal) | passive | Right terminal of the single-line unidirectional TVS diode; the datasheet gives reverse working voltage VRWM of 5 V maximum, breakdown voltage VBR of 6.5 V minimum, and clamping voltage of 10 V at Ipp = 1 A and 14 V at Ipp = 4 A (8x20 us pulse). |

## CAD (KiCad official)

- Symbol: `TPPESD5V0U1UL`
- Footprint: `Diode_SMD:D_SOD-882`
- 3D model: DFN1006-2L (KiCad packages3D, STEP)
- 3D model files: `tppesd5v0u1ul-etched.step` / `tppesd5v0u1ul-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tppesd5v0u1ul.step` / `tppesd5v0u1ul.glb` are the bare package body.
