WE05D9-B

Wayon · ESD And Surge Protection (TVS/ESD) · SOD-923

WE05D9-B from Wayon, in a SOD-923. 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 One of the two terminals of the single-line TVS, which protects one line with a 5 V working voltage (VRWM 5.0 V max) and a 6.0 V minimum reverse breakdown at IT = 1 mA; the datasheet does not state whether this terminal is the anode or cathode.
2 2 passive The other terminal of the single-line TVS, which clamps to 10 V typical at 1 A and 12 V maximum at 5 A (8/20 µs); the datasheet does not state whether this terminal is the anode or cathode.
