SMF22CA from LGE, 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 | A1 | passive | Bidirectional TVS terminal 1 (SMF22CA, 22 V working voltage, 200 W peak pulse power at 10/1000 μs); the device is symmetric and has no cathode band. |
| 2 | A2 | passive | Bidirectional TVS terminal 2 (SMF22CA, 22 V working voltage, 200 W peak pulse power at 10/1000 μs); the device is symmetric and has no cathode band. |
