H3V3LD5B

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

H3V3LD5B from hongjiacheng, 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 A1 passive Bi-directional ESD protection terminal (cathode-band side of the SOD-523 body) with 3.3V max reverse working voltage, interchangeable with the other terminal and connected to the protected line.
2 A2 passive Bi-directional ESD protection terminal (opposite end from the cathode band) with 3.3V max reverse working voltage, connected to ground or the second line being protected.

CAD (KiCad official)

  • Symbol: H3V3LD5B
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: h3v3ld5b-etched.step / h3v3ld5b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); h3v3ld5b.step / h3v3ld5b.glb are the bare package body.
