PESD3V3U1UL

TECH PUBLIC · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

PESD3V3U1UL from TECH PUBLIC, in a DFN1006-2. 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 1 passive Terminal 1 of the uni-directional 1-line TVS diode, shown as one side of the diode symbol in the datasheet's terminal connection diagram; the 0.45 pF typical junction capacitance is specified from Pin 1 to Pin 2 (0.5 pF max at VR = 0 V, f = 1 MHz).
2 2 passive Terminal 2 of the uni-directional 1-line TVS diode, the opposite side of the diode symbol; the device has a reverse working voltage of 3.3 V max, a breakdown voltage of 4.2 V min at IT = 1 mA, and a reverse leakage current of 0.08 uA max at VRWM = 3.3 V.

CAD (KiCad official)

  • Symbol: PESD3V3U1UL
  • Footprint: Diode_SMD:D_SOD-882
  • 3D model: DFN1006-2 (KiCad packages3D, STEP)
  • 3D model files: pesd3v3u1ul-etched.step / pesd3v3u1ul-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd3v3u1ul.step / pesd3v3u1ul.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 a3fa4f1d337ff34e, 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).
