WE05DUCF-B

Wayon · ESD Protection Devices · DFN1006-2L

WE05DUCF-B from Wayon, in a DFN1006-2L. 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 Pin1 passive Terminal 1 of the TVS device, which protects one I/O or power line; the datasheet gives no pin-specific function or electrical limit for this terminal.
2 Pin2 passive Terminal 2 of the TVS device, which protects one I/O or power line; the datasheet gives no pin-specific function or electrical limit for this terminal.
