TPESD0502BA

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-523

TPESD0502BA from TECH PUBLIC, in a SOT-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 I/O1 passive Protected line 1 (TVS diode cathode); 5V max reverse working voltage, 0.6pF max to ground, 0.35pF max between I/O pins.
2 I/O2 passive Protected line 2 (TVS diode cathode); 5V max reverse working voltage, 0.6pF max to ground, 0.35pF max between I/O pins.
3 GND power_in Common anode of both TVS diodes, ground reference; ESD rated ±20kV air and ±15kV contact per IEC 61000-4-2.

CAD (KiCad official)

  • Symbol: TPESD0502BA
  • Footprint: Package_TO_SOT_SMD:SOT-523
  • 3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 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: tpesd0502ba-etched.step / tpesd0502ba-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesd0502ba.step / tpesd0502ba.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 86e4dca86d344f04, retrieved 2026-10-19, 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).
