BAT854SWF

Nexperia · Schottky Barrier Diodes (SBD) · SOT-323-3

BAT854SWF from Nexperia, in a SOT-323-3. 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 a1 passive Anode of diode 1; the datasheet gives no electrical limit for this pin itself, the ratings apply per diode (VR max 40 V, IF max 200 mA).
2 k2 passive Cathode of diode 2; the datasheet gives no electrical limit for this pin itself, the ratings apply per diode (VR max 40 V, IF max 200 mA).
3 k1, a2 passive Common node joining cathode k1 of diode 1 to anode a2 of diode 2 (series configuration); the datasheet gives no separate electrical limit for this node.

CAD (KiCad official)

  • Symbol: BAT854SWF
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323-3 (KiCad packages3D, STEP)
  • 3D model files: bat854swf-etched.step / bat854swf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bat854swf.step / bat854swf.glb are the bare package body.
