MURF1040GCT

DIYI Elec Tech · Diodes - Fast Recovery Rectifiers · TO-220AB-3

MURF1040GCT from DIYI Elec Tech, in a TO-220AB-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 the first rectifier diode (10 A total average forward current, 400 V VRRM/VDC), per the center-tap symbol on the package drawing.
2 K passive Common cathode of both diodes (center pin), shown joined to the two diode cathodes in the schematic symbol.
3 A2 passive Anode of the second rectifier diode (10 A total average forward current, 400 V VRRM/VDC), per the center-tap symbol on the package drawing.

CAD (KiCad official)

  • Symbol: MURF1040GCT
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB-3 (KiCad packages3D, STEP)
  • 3D model files: murf1040gct-etched.step / murf1040gct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); murf1040gct.step / murf1040gct.glb are the bare package body.
