BAS70-7-F

Diodes Incorporated · Schottky Diodes · SOT-23

BAS70-7-F from Diodes Incorporated, 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 A passive Schottky diode anode (bottom-left pad in the top-view BAS70 diagram); the diode is rated for VR 70 V and IFM 70 mA.
2 NC unconnected No internal connection on the single-diode BAS70 (bottom-right pad in the top-view diagram has no diode connected).
3 K passive Schottky diode cathode (top pad in the top-view BAS70 diagram); the diode is rated for VR 70 V and IFM 70 mA.

CAD (KiCad official)

  • Symbol: BAS70-7-F
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bas70-7-f-etched.step / bas70-7-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas70-7-f.step / bas70-7-f.glb are the bare package body.
