WS05DLC-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 5.0 V rated stand-off voltage (VWM) and 6.0 V minimum breakdown at 1 mA, and characteristics apply in both directions. |
| 2 | 2 | passive | Bidirectional TVS terminal; connects to the protected line's return or ground, and polarity is interchangeable with pin 1 with up to 350 W peak pulse power (8/20 µs). |
