SMBJ110A from LGE, 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 | K | passive | Cathode end of the unidirectional SMBJ110A TVS, marked by the color band, connected to the protected line (VRWM 110 V, 600 W 10/1000 µs peak pulse power). |
