ESDAVLC5-1BF4

STMicroelectronics · ESD And Surge Protection (TVS/ESD) · 0201

ESDAVLC5-1BF4 from STMicroelectronics, in a 0201. 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 I/O1 passive Bidirectional ESD protection terminal (pin 1, marked end of the package) connected to the protected line, with working voltage VRM of -5.3 V to 5.3 V and breakdown voltage VBR of 5.8 V min at 1 mA.
2 I/O2 passive Second terminal of the bidirectional TVS diode, connected to the other side (typically ground or return) of the protected line, with the same ±5.3 V working voltage and ±12 kV contact / ±30 kV air IEC 61000-4-2 rating.

CAD (KiCad official)

  • Symbol: ESDAVLC5-1BF4
  • Footprint: Diode_SMD:D_0201_0603Metric
  • 3D model: 0201, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.3 mm nominal 01005 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: esdavlc5-1bf4-etched.step / esdavlc5-1bf4-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esdavlc5-1bf4.step / esdavlc5-1bf4.glb are the bare package body.
