TPESD3V3U1UB

TECH PUBLIC · ESD Protection Devices · SOD-523

TPESD3V3U1UB from TECH PUBLIC, in a SOD-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 Pin 1 (diode terminal) passive One terminal of the uni-directional 1-line TVS diode; the datasheet references Pin 1 to Pin 2 for junction capacitance (0.5 pF typical, 0.9 pF maximum at VR = 0 V, f = 1 MHz).
2 Pin 2 (diode terminal) passive Other terminal of the uni-directional 1-line TVS diode; the datasheet references Pin 1 to Pin 2 for junction capacitance (0.5 pF typical, 0.9 pF maximum at VR = 0 V, f = 1 MHz), with a 3.3 V reverse working voltage and 14 V clamping voltage at Ipp = 4 A (8/20 µs).

CAD (KiCad official)

  • Symbol: TPESD3V3U1UB
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: tpesd3v3u1ub-etched.step / tpesd3v3u1ub-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpesd3v3u1ub.step / tpesd3v3u1ub.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 6af4fb5868d509f4, 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).
