NUP2105LT1G

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

NUP2105LT1G from TECH PUBLIC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IO1 passive Bidirectional TVS I/O line 1; one TVS diode connected between this pin and Pin 3 (common), VRWM = 24 V, VC = 33 V typ / 43 V max at Ipp = 1 A (8×20 µs pulse), CJ = 25 pF typ (VR = 0 V, f = 1 MHz, Pin 1 to Pin 2).
2 IO2 passive Bidirectional TVS I/O line 2; one TVS diode connected between this pin and Pin 3 (common), VRWM = 24 V, VC = 33 V typ / 43 V max at Ipp = 1 A (8×20 µs pulse), CJ = 25 pF typ (VR = 0 V, f = 1 MHz, Pin 1 to Pin 2).
3 GND power_in Common cathode / GND reference terminal shared by both bidirectional TVS diodes; VESD per IEC 61000-4-2 (Air) ±30 kV, (Contact) ±30 kV; peak pulse power 300 W (8/20 µs).

CAD (KiCad official)

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