NUP1301

UMW · ESD And Surge Protection (TVS/ESD) · SOT-23

NUP1301 from UMW, 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 ANODE passive Anode of one of the two diodes in the device; the datasheet states that transients exceeding the diode forward voltage plus the reference voltage are directed to the supply rail or ground, with 0.9 pF maximum diode capacitance.
2 CATHODE passive Cathode of the second diode in the device; the datasheet rates IEC61000-4-2 (Level 4) protection at 8.0 kV contact and 15 kV air.
3 CATHODE/ANODE passive Common terminal shared by both diodes; the datasheet gives a 70 V reverse voltage and 215 mA forward current rating for the device.

  • Symbol: NUP1301
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: nup1301-etched.step / nup1301-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nup1301.step / nup1301.glb are the bare package body.

Provenance

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

  • Datasheet: UMW datasheet (7 pp, sha256 0a65a436e57906d2, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
