ESD5452E-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 line 1 of the bi-directional TVS, rated for ±5V max reverse stand-off voltage and ±30kV IEC61000-4-2 contact and air discharge. |
| 2 | I/O2 | passive | Protected line 2 of the bi-directional TVS, rated for ±5V max reverse stand-off voltage and ±30kV IEC61000-4-2 contact and air discharge. |
| 3 | GND | power_in | Common ground reference for both TVS lines, which clamp to about 9V typ. at IPP = 16A (TLP). |
