PESD5V0S1BBN-DW from DOWO, 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 | IO1 | bidirectional | Connects to I/O line 1 of the bi-directional protected line, which the device clamps against ESD (IEC 61000-4-2 Level 4, ±25kV contact and air) with a working voltage of 5V. |
| 2 | IO2 | bidirectional | Connects to the opposite I/O terminal of the bi-directional protected line; the datasheet pin table text for this entry is truncated after "Connect to IO". |
