SD22-01FTG from Littelfuse, in a SOD-323. 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 | 1 | passive | Terminal 1 of the unidirectional SD22 TVS diode; the text does not state whether it is the I/O line or ground, and the tape-and-reel section marks Pin1 orientation. |
| 2 | 2 | passive | Terminal 2 of the unidirectional SD22 TVS diode; the text does not state whether it is the I/O line or ground. |
