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). |
