WS05DLC-B

Wayon · ESD And Surge Protection (TVS/ESD) · SOD-323

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).
