Liown · ESD And Surge Protection (TVS/ESD) · SOD-123
SJD12A110L01 from Liown, in a SOD-123. 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, marked by the cathode band on this unidirectional part; reverse stand-off voltage VR 110V, breakdown 122V to 135V at 1mA. |
| 2 | A | passive | Anode, the terminal opposite the cathode band; the part clamps at a maximum of 177V at 1.2A peak pulse current (8/20μs). |
