BAS40-04HMFHT116

ROHM Semicon · Schottky Barrier Diodes (SBD) · SOT-23

BAS40-04HMFHT116 from ROHM Semicon, 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 Anode terminal of one of the two Schottky diodes; the datasheet rates the part for 40 V repetitive peak reverse voltage and 120 mA average forward rectified current per diode.
2 Cathode/Anode passive Shared cathode/anode terminal joining the two diodes in the internal series configuration; the datasheet gives no separate function for this pin beyond the drawing label.
3 Cathode passive Cathode terminal of the second Schottky diode; the datasheet rates the part for 40 V reverse voltage and 120 mA direct current per diode.

CAD (KiCad official)

  • Symbol: BAS40-04HMFHT116
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bas40-04hmfht116-etched.step / bas40-04hmfht116-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bas40-04hmfht116.step / bas40-04hmfht116.glb are the bare package body.

Provenance

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