ESDA0504T5

Leiditech · ESD And Surge Protection (TVS/ESD) · SOT-553

ESDA0504T5 from Leiditech, in a SOT-553. 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 IO1 passive Protected line 1 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
2 GND power_in Common ground node of the TVS array, tied to the centre node joining the diode pairs in the pin configuration drawing.
3 IO3 passive Protected line 3 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
4 IO4 passive Protected line 4 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
5 IO5 passive Protected line 5 of the TVS array, rated for 5V working voltage (VRWM) and ±15kV air / ±8kV contact ESD per IEC 61000-4-2.

CAD (KiCad official)

  • Symbol: ESDA0504T5
  • Footprint: Package_TO_SOT_SMD:SOT-553
  • 3D model: SOT-553 (KiCad packages3D, STEP)
  • 3D model files: esda0504t5-etched.step / esda0504t5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esda0504t5.step / esda0504t5.glb are the bare package body.

Provenance

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

  • Datasheet: Leiditech datasheet (3 pp, sha256 0b814e972e8d07f2, retrieved 2026-10-22, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
