# GG0402050R3C2P

**Kyocera AVX** · ESD And Surge Protection (TVS/ESD) · 0402

GG0402050R3C2P from Kyocera AVX, in a 0402. 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 | Terminal 1 of the bi-directional TVS diode (I/O 1); connect to the protected signal line, rated 5.0V Vrwm with 0.3pF nominal capacitance. |
| 2 | 2 | passive | Terminal 2 of the bi-directional TVS diode (I/O 2); connect to ground or the other side of the protected line, as protection is bi-directional with no polarity. |

## CAD (KiCad official)

- Symbol: `GG0402050R3C2P`
- Footprint: `Diode_SMD:D_0402_1005Metric`
- 3D model: 0402, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.4 mm nominal _0402_ height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `gg0402050r3c2p-etched.step` / `gg0402050r3c2p-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `gg0402050r3c2p.step` / `gg0402050r3c2p.glb` are the bare package body.
