DW03D-B-S-ES from ElecSuper, in a SOD-323. 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 the protected bi-directional data line IO1; the datasheet rates all pins to withstand ±30kV IEC61000-4-2 ESD with a 3.3V reverse stand-off voltage (VRWM). |
| 2 | IO2 | bidirectional | Connects to the protected bi-directional data line IO2; the datasheet rates all pins to withstand ±30kV IEC61000-4-2 ESD with a 3.3V reverse stand-off voltage (VRWM). |
