WILLSEMI Will Semicon · ESD And Surge Protection (TVS/ESD) · SOD-323F
ESD56131W-2 from WILLSEMI Will Semicon, in a SOD-323F. 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 | Pin1 | passive | One terminal of the bi-directional TVS, rated for a reverse stand-off voltage of ±4.6V and ±30kV ESD (contact and air) per IEC61000-4-2; the datasheet gives no pin-specific limits. |
| 2 | Pin2 | passive | The other terminal of the bi-directional TVS, rated for a reverse stand-off voltage of ±4.6V and ±30kV ESD (contact and air) per IEC61000-4-2; the datasheet gives no pin-specific limits. |
