ESDA25W

TECH PUBLIC · ESD Protection Devices · SOT-323

ESDA25W from TECH PUBLIC, in a SOT-323. 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 Protected line 1 (diode anode in the schematic symbol), uni-directional TVS channel with 24V max reverse working voltage, 25V min breakdown at 1mA, and 350W peak pulse power (8/20µs).
2 I/O2 passive Protected line 2 (diode anode in the schematic symbol), uni-directional TVS channel with 24V max reverse working voltage, 25V min breakdown at 1mA, and 350W peak pulse power (8/20µs).
3 COMMON passive Common cathode node of the two TVS diodes in the schematic symbol, shared by both protected lines (datasheet does not label its function further).

CAD (KiCad official)

  • Symbol: ESDA25W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: esda25w-etched.step / esda25w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); esda25w.step / esda25w.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 eac0e0b348d73353, retrieved 2026-11-04, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
