WILLSEMI Will Semicon · ESD And Surge Protection (TVS/ESD) · SOT-23
ESD5682E12-3 from WILLSEMI Will Semicon, 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 | I/O1 | passive | Protected I/O line 1 of the 2-line uni-directional TVS, rated for a 12 V max reverse stand-off voltage (VRWM) with ±30 kV IEC61000-4-2 contact and air ESD protection. |
| 2 | I/O2 | passive | Protected I/O line 2 of the 2-line uni-directional TVS, rated for a 12 V max reverse stand-off voltage (VRWM) with ±30 kV IEC61000-4-2 contact and air ESD protection. |
| 3 | GND | power_in | Ground reference pin and common return for the two TVS channels. |
