PESD15VS1UB-ES from ElecSuper, in a SOD-523. 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 | IO | bidirectional | Connect to the IO line to be protected; the part is a unidirectional TVS rated for ±30 kV IEC 61000-4-2 contact and air discharge with a maximum reverse stand-off voltage VRWM of 15.0 V. |
| 2 | GND | power_in | Connect to GND, the reference return for the protected line. |
