Wayon · ESD And Surge Protection (TVS/ESD) · SOD-323
WS03DLC-B from Wayon, 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 | 1 | passive | Bidirectional TVS terminal; protects one power or I/O line with 3.3V rated stand-off voltage (VWM), 4.0V minimum breakdown at 1mA, and electrical characteristics apply in both directions, so it may be connected to the line or to ground. |
| 2 | 2 | passive | Bidirectional TVS terminal; protects one power or I/O line with 3.3V rated stand-off voltage (VWM), 4.0V minimum breakdown at 1mA, and electrical characteristics apply in both directions, so it may be connected to the line or to ground. |
