# TPE03GHC

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOD-323

TPE03GHC from TECH PUBLIC, in a SOD-323. 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 | A1 | passive | One terminal of the 1-line bi-directional TVS diode, connected to the protected data or power line (3.3V max reverse working voltage, ±30kV IEC 61000-4-2 ESD). |
| 2 | A2 | passive | Other terminal of the bi-directional TVS diode, interchangeable with the first and typically connected to ground (3.3V max reverse working voltage, 450W 8/20µs peak pulse power). |

## CAD (KiCad official)

- Symbol: `TPE03GHC`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `tpe03ghc-etched.step` / `tpe03ghc-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpe03ghc.step` / `tpe03ghc.glb` are the bare package body.
