SBAS40LT1G

onsemi · Schottky Diodes · SOT-23

SBAS40LT1G from onsemi, 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 ANODE passive Schottky diode anode; the device is rated for 40 V reverse voltage and 120 mA forward continuous current.
2 NC unconnected No connection; the datasheet specifies this pin as NO CONNECTION for STYLE 8.
3 CATHODE passive Schottky diode cathode; the device is rated for 40 V reverse voltage and 120 mA forward continuous current.

CAD (KiCad official)

  • Symbol: SBAS40LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sbas40lt1g-etched.step / sbas40lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sbas40lt1g.step / sbas40lt1g.glb are the bare package body.
