UMZ27NUM-TP

TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-323

UMZ27NUM-TP from TECH PUBLIC, in a SOT-323. 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 anode); 22V reverse working voltage, 25V min breakdown at 1mA, ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
2 I/O2 passive Protected line 2 (TVS diode anode); 22V reverse working voltage, 25V min breakdown at 1mA, ±15kV air / ±8kV contact ESD per IEC 61000-4-2.
3 COMMON passive Common node of the two uni-directional TVS diodes (shared by both lines in the schematic).

CAD (KiCad official)

  • Symbol: UMZ27NUM-TP
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: umz27num-tp-etched.step / umz27num-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); umz27num-tp.step / umz27num-tp.glb are the bare package body.

Provenance

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

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 8a3328bdfb7e739b, 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).
