SM05L

Wild Goose · ESD And Surge Protection (TVS/ESD) · SOT-23

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.
