# LC05CD

**Shenzhen Jinkaisheng Elec** · ESD And Surge Protection (TVS/ESD) · SOT-23

LC05CD from Shenzhen Jinkaisheng Elec, in a SOT-23. 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 | I/O1 | passive | Protected I/O line 1, steered through the diode array to the TVS (350 W peak pulse power per line, 8/20µs; VRWM 5V max). |
| 2 | I/O2 | passive | Protected I/O line 2, steered through the diode array to the TVS (350 W peak pulse power per line, 8/20µs; VRWM 5V max). |
| 3 | GND | power_in | Common node on the TVS anode side of the diode array, which serves as the ground reference for the two protected I/O lines. |

## CAD (KiCad official)

- Symbol: `LC05CD`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lc05cd-etched.step` / `lc05cd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lc05cd.step` / `lc05cd.glb` are the bare package body.
