# P6SMB6.8CA

**UMW** · ESD And Surge Protection (TVS/ESD) · SMB

P6SMB6.8CA from UMW, in a SMB. 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 | Bi-directional TVS terminal with no polarity marking; the datasheet gives 600 W peak pulse power (10/1000 µs) and 5.8 V stand-off voltage for this 6.8 V part, and the terminal can connect to either side of the protected line. |
| 2 | A2 | passive | Second bi-directional TVS terminal with no polarity marking; the datasheet gives 600 W peak pulse power (10/1000 µs) and 5.8 V stand-off voltage for this 6.8 V part, and the terminal can connect to either side of the protected line. |

## CAD (KiCad official)

- Symbol: `P6SMB6.8CA`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB (KiCad packages3D, STEP)
- 3D model files: `p6smb6-8ca-etched.step` / `p6smb6-8ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `p6smb6-8ca.step` / `p6smb6-8ca.glb` are the bare package body.
