SK315U

DIYI Elec Tech · Schottky Barrier Diodes (SBD) · SMB

SK315U from DIYI Elec Tech, in a SMB. 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, marked by the color band on the package; the datasheet states 'Polarity: Color band denotes cathode end', with 20-150 V... see review note for rating by type.
2 A passive Anode terminal of the Schottky barrier rectifier (3.0 A average rectified output current, VFM 0.5-0.92 V at IF=3.0 A depending on type).

CAD (KiCad official)

  • Symbol: SK315U
  • Footprint: Diode_SMD:D_SMB
  • 3D model: SMB (KiCad packages3D, STEP)
  • 3D model files: sk315u-etched.step / sk315u-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sk315u.step / sk315u.glb are the bare package body.
