PESD3V3L2BT-FS

FUXINSEMI · ESD Protection Devices · SOT-23

PESD3V3L2BT-FS from FUXINSEMI, in a SOT-23. 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 I/O line 1 (bidirectional TVS to pin 3), breakdown 4.0 V to 6.0 V at IT=1mA, clamping max 7 V at IPP=1A and 12 V at IPP=38A (8/20µs).
2 I/O2 passive Protected I/O line 2 (bidirectional TVS to pin 3), breakdown 4.0 V to 6.0 V at IT=1mA, clamping max 7 V at IPP=1A and 12 V at IPP=38A (8/20µs).
3 COMMON passive Common pin of the diode array, reference for Pin1/Pin2 to Pin3 protection; the datasheet does not label it as GND, and pin 1 to pin 2 breakdown is 8.0 V to 12 V.

CAD (KiCad official)

  • Symbol: PESD3V3L2BT-FS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: pesd3v3l2bt-fs-etched.step / pesd3v3l2bt-fs-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); pesd3v3l2bt-fs.step / pesd3v3l2bt-fs.glb are the bare package body.

Provenance

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

  • Datasheet: FUXINSEMI datasheet (4 pp, sha256 1bb2fa1a18263eb4, 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).
