ESD5VFBD523

YFW · ESD And Surge Protection (TVS/ESD) · SOD-523

ESD5VFBD523 from YFW, in a SOD-523. 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 Terminal 1 of the bidirectional TVS, which protects one I/O or power line with a reverse stand-off voltage (VRWM) of 5.0 V max, breakdown 5.6 V min to 7.4 V max at 1 mA, clamping 9.5 V max at IPP = 8 A (tP = 8/20 µs), and 100 W peak pulse power.
2 2 passive Terminal 2 of the bidirectional TVS, which has the same limits as pin 1: VRWM 5.0 V max, breakdown 5.6 V min to 7.4 V max at 1 mA, clamping 9.5 V max at 8 A, and ESD protection rated ±30 kV contact and air per IEC 61000-4-2.

  • Symbol: ESD5VFBD523
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: esd5vfbd523-etched.step / esd5vfbd523-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esd5vfbd523.step / esd5vfbd523.glb are the bare package body.

Provenance

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