# SMBJ6.8CA

**UMW** · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

SMBJ6.8CA from UMW, in a SMB(DO-214AA). 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 1; the CA type has no polarity and no cathode band marking, and it can connect to either side of the line (VWM 5.80 V, 600 W peak pulse power at 10/1000 µs). |
| 2 | A2 | passive | Bi-directional TVS terminal 2; the CA type has no polarity and no cathode band marking, and it can connect to either side of the line (VWM 5.80 V, 600 W peak pulse power at 10/1000 µs). |

## CAD (KiCad official)

- Symbol: `SMBJ6.8CA`
- Footprint: `Diode_SMD:D_SMB`
- 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
- 3D model files: `smbj6-8ca-etched.step` / `smbj6-8ca-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `smbj6-8ca.step` / `smbj6-8ca.glb` are the bare package body.
