ESDAULC6-1U2

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

ESDAULC6-1U2 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 K passive Cathode (pin 1, marked pad) connects to the protected data line or I/O, which has a 6 V min breakdown voltage at 1 mA, 3 V stand-off voltage and 0.8 pF typ line capacitance.
2 A passive Anode connects to ground as the return of the unidirectional TVS diode, which is rated for IEC 61000-4-2 ±8 kV contact and ±15 kV air discharge.

CAD (KiCad official)

  • Symbol: ESDAULC6-1U2
  • Footprint: Diode_SMD:D_0201_0603Metric
  • 3D model: 0201 (KiCad packages3D, STEP)
  • 3D model files: esdaulc6-1u2-etched.step / esdaulc6-1u2-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esdaulc6-1u2.step / esdaulc6-1u2.glb are the bare package body.

Provenance

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

  • Datasheet: STMicroelectronics datasheet (10 pp, sha256 40aaec7e472abe81, retrieved 2026-10-21, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
