BAT54-HE3-08

Vishay Intertech · Schottky Barrier Diodes (SBD) · SOT-23-3

BAT54-HE3-08 from Vishay Intertech, in a SOT-23-3. 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 A passive Anode of the single Schottky diode (BAT54), with a 30 V repetitive peak reverse voltage and 200 mA continuous forward current rating.
2 NC unconnected Not connected internally in the single BAT54 configuration; the top-view diagram shows no connection to the diode.
3 K passive Cathode of the single Schottky diode (BAT54), with a 30 V repetitive peak reverse voltage and 200 mA continuous forward current rating.

CAD (KiCad official)

  • Symbol: BAT54-HE3-08
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: bat54-he3-08-etched.step / bat54-he3-08-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat54-he3-08.step / bat54-he3-08.glb are the bare package body.
