WS58P6SMB

Wayon · ESD And Surge Protection (TVS/ESD) · SMB(DO-214AA)

WS58P6SMB from Wayon, in a SMB(DO-214AA). 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 PIN 1 passive Terminal 1 of the unidirectional WS58P6SMB TVS (VRWM 58 V, VBR 64.4-71.2 V at 1 mA, Vc 93.6 V at 6.4 A Ipp); the cathode band marks the cathode terminal on unidirectional parts.
2 PIN 2 passive Terminal 2 of the unidirectional WS58P6SMB TVS (600 W peak pulse power at 10/1000 µs, max leakage 1 µA at 58 V); the cathode band marks the cathode terminal on unidirectional parts.

CAD (KiCad official)

  • Symbol: WS58P6SMB
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB(DO-214AA) (KiCad packages3D, STEP)
  • 3D model files: ws58p6smb-etched.step / ws58p6smb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ws58p6smb.step / ws58p6smb.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
