SODJ18A-SH from LRC, in a SOD-123FL. 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 terminal of the unidirectional TVS, marked by the cathode band, connected to the protected I/O line (VRWM 18 V, VBR 20 V min to 22.1 V max at 1 mA, VC 29.2 V max). |
| 2 | A | passive | Anode terminal of the unidirectional TVS, on the side without the cathode band, normally connected to ground (200 W peak pulse power at 10/1000 µs). |
