AQ4024-01FTG

Littelfuse · ESD And Surge Protection (TVS/ESD) · SOD-323

AQ4024-01FTG from Littelfuse, in a SOD-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 Pin 1 passive Cathode side of the unidirectional TVS diode (cathode polarity marking for unidirectional parts); protected line connection, 24V reverse standoff (VRWM) and 26V breakdown at 1mA, Pin 1 to Pin 2.
2 Pin 2 passive Second terminal of the TVS diode (anode side for the unidirectional AQ4024-01FTG), typically ground reference; ±30kV ESD and 7A (8/20µs) surge protection between Pin 1 and Pin 2.

CAD (KiCad official)

  • Symbol: AQ4024-01FTG
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: aq4024-01ftg-etched.step / aq4024-01ftg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aq4024-01ftg.step / aq4024-01ftg.glb are the bare package body.
