SM05L from Wild Goose, in a SOT-23. 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 | CATHODE 1 | passive | Cathode of the first unidirectional transil diode, rated for a reverse stand-off voltage of 5.0 V max, with 0.25 pF typ and 0.3 pF max junction capacitance from pin 1 or 2 to pin 3. |
| 2 | CATHODE 2 | passive | Cathode of the second unidirectional transil diode, rated for a reverse stand-off voltage of 5.0 V max, with 0.25 pF typ and 0.3 pF max junction capacitance from pin 1 or 2 to pin 3. |
| 3 | COMMON ANODE | passive | Common anode shared by both diodes, which protects two separate lines using only one package. |
