AQHV12-01LTG

Littelfuse · TVS · SOD-523

AQHV12-01LTG from Littelfuse, in a SOD-523. 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/O passive Protected line (cathode side of the unidirectional TVS); standoff 12.0V max, breakdown 13.3V min at 1mA, clamps to 26V max at 10A (8/20µs) referenced to GND.
2 GND power_in Ground reference (anode side) for the I/O-to-GND clamp, rated ±30kV IEC 61000-4-2 contact and air discharge.

CAD (KiCad official)

  • Symbol: AQHV12-01LTG
  • Footprint: Diode_SMD:D_SOD-523
  • 3D model: SOD-523 (KiCad packages3D, STEP)
  • 3D model files: aqhv12-01ltg-etched.step / aqhv12-01ltg-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); aqhv12-01ltg.step / aqhv12-01ltg.glb are the bare package body.
