VDA1120NTA

AnaSem · Voltage Reference · SOT-23

VDA1120NTA from AnaSem, 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 VOUT output Detector output. N-channel open-drain (requires ~100 kΩ pull-up to VIN); goes low when VIN < VDET and releases high when VIN > VREL. Absolute output range VSS−0.3 V to VIN+0.3 V; sink capability ~1.5 mA at VDS=0.5 V with VIN=1.0 V.
2 VSS power_in Power ground / negative supply reference. Common return for VIN sense and open-drain output.
3 VIN power_in Voltage input being monitored and used as device supply. Operating range 0.7 V to 6.0 V (absolute max −0.3 V to +7.0 V). Compared against internal 1.1 V reference (VDET, ±2%).

CAD (KiCad official)

  • Symbol: VDA1120NTA
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: vda1120nta-etched.step / vda1120nta-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); vda1120nta.step / vda1120nta.glb are the bare package body.

Provenance

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

  • Datasheet: AnaSem datasheet (18 pp, sha256 4f0f97f14795b51f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
