# SD05C.TCT

**SEMTECH** · Global Sourcing Parts · SOD-323

SD05C.TCT from SEMTECH, 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 | 1 | passive | One of two symmetrical terminals of the bidirectional TVS diode, which protects one data, I/O or power line to ±15 kV air and ±8 kV contact per IEC 61000-4-2 and is rated for a 5 V working voltage on the SD05C. |
| 2 | 2 | passive | The other symmetrical terminal of the bidirectional TVS diode, which has no cathode band so it can be used on lines whose signal polarity swings above and below ground, with 350 W peak pulse power (8/20 µs). |

## CAD (KiCad official)

- Symbol: `SD05C.TCT`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `sd05c-tct-etched.step` / `sd05c-tct-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sd05c-tct.step` / `sd05c-tct.glb` are the bare package body.
