WE05DRF-B

Wayon · ESD Protection Devices · DFN1006-2L

WE05DRF-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 1 passive One of two terminals of the TVS that protects one I/O or power line, rated for a 5 V working voltage (VRWM) with 0.3 pF typical junction capacitance; the text does not state whether this terminal is the anode or cathode.
2 2 passive One of two terminals of the TVS that protects one I/O or power line, rated for a 5 V working voltage (VRWM) with 0.3 pF typical junction capacitance; the text does not state whether this terminal is the anode or cathode.

CAD (KiCad official)

  • Symbol: WE05DRF-B
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2L (KiCad packages3D, STEP)
  • 3D model files: we05drf-b-etched.step / we05drf-b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); we05drf-b.step / we05drf-b.glb are the bare package body.
