NUP2105LT1G-MS

MSKSEMI · ESD Protection Devices · SOT-23

NUP2105LT1G-MS from MSKSEMI, 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 line 1 connected to the steering/TVS diode structure, with reverse working voltage VRWM of 24 V, breakdown voltage VBR of 27 V at 1 mA, and ±30 kV IEC 61000-4-2 ESD rating.
2 I/O2 passive Protected line 2 connected to the steering/TVS diode structure, with reverse working voltage VRWM of 24 V, breakdown voltage VBR of 27 V at 1 mA, and ±30 kV IEC 61000-4-2 ESD rating.
3 COMMON passive Common node shared by both protection diode pairs, shown as pin 3 on the package drawing; the datasheet does not label it as ground.

CAD (KiCad official)

  • Symbol: NUP2105LT1G-MS
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: nup2105lt1g-ms-etched.step / nup2105lt1g-ms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); nup2105lt1g-ms.step / nup2105lt1g-ms.glb are the bare package body.

Provenance

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

  • Datasheet: MSKSEMI datasheet (5 pp, sha256 18971e6dc5f3c1ea, retrieved 2026-10-28, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
