WS4.5D3HP

Wayon · TVS · SOD-323F

WS4.5D3HP from Wayon, in a SOD-323F. 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 Pin 1 of the SOD-323F top view protects one I/O or power line, but the datasheet does not state its polarity or function, so it is not identified as anode or cathode in the text.
2 2 passive Pin 2 of the SOD-323F top view is the other terminal of the protected line, but the datasheet does not state its polarity or function, so it is not identified as anode or cathode in the text.
