ACDBC340-HF

Comchip · Schottky Barrier Diodes (SBD) · DO-214AB

ACDBC340-HF from Comchip, in a DO-214AB. 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 K passive Cathode, the terminal marked by the cathode band on the DO-214AB (SMC) body; the device blocks up to 40 V (VRRM) for ACDBC340-HF and carries 3 A average forward current.
2 A passive Anode, the terminal opposite the cathode band; forward voltage is max 0.55 V at IF=3A, 25°C for ACDBC340-HF.

CAD (KiCad official)

  • Symbol: ACDBC340-HF
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB (KiCad packages3D, STEP)
  • 3D model files: acdbc340-hf-etched.step / acdbc340-hf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); acdbc340-hf.step / acdbc340-hf.glb are the bare package body.
