# SD05T1G-P

**TECH PUBLIC** · ESD Protection Devices · SOD-323

SD05T1G-P 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 | IO | bidirectional | Protected data or power line; the TVS clamps transients on this line with a 5 V reverse working voltage and 350 W peak pulse power (8/20µs). |
| 2 | GND | power_in | Ground terminal of the unidirectional TVS diode, serving as the clamping return path for the protected line. |

## CAD (KiCad official)

- Symbol: `SD05T1G-P`
- Footprint: `Diode_SMD:D_SOD-323`
- 3D model: SOD-323 (KiCad packages3D, STEP)
- 3D model files: `sd05t1g-p-etched.step` / `sd05t1g-p-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sd05t1g-p.step` / `sd05t1g-p.glb` are the bare package body.
