TPE0552R3

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

TPE0552R3 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 of the 2-line bi-directional TVS, with reverse working voltage 5V max and breakdown 6.5V min to 8.5V max at 1mA, connected through the diode to pin 3.
2 I/O2 passive Protected line 2 of the 2-line bi-directional TVS, with reverse working voltage 5V max and breakdown 6.5V min to 8.5V max at 1mA, connected through the diode to pin 3.
3 COMMON passive Common node of the two TVS diode branches (top pin in the diagram), with junction capacitance to pins 1 and 2 of 15pF typ and 20pF max at 0V, 1MHz.

CAD (KiCad official)

  • Symbol: TPE0552R3
  • 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: tpe0552r3-etched.step / tpe0552r3-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tpe0552r3.step / tpe0552r3.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 fdecb09e0985bf87, retrieved 2026-10-21, 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).
