MBR1040CT

Shandong Jingdao Microelectronics · Schottky Diodes · TO-220AB

MBR1040CT from Shandong Jingdao Microelectronics, in a TO-220AB. 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 diode 1 (per-diode 5 A average forward current, 40 V VRRM for MBR1040CT, VF 0.70 V at 5 A).
2 K passive Common cathode of both diodes, also connected to the mounting tab (per-device 10 A average forward current, 40 V maximum DC blocking voltage).
3 A2 passive Anode of diode 2 (per-diode 5 A average forward current, 40 V VRRM for MBR1040CT, VF 0.70 V at 5 A).

CAD (KiCad official)

  • Symbol: MBR1040CT
  • Footprint: Package_TO_SOT_THT:TO-220-3_Vertical
  • 3D model: TO-220AB (KiCad packages3D, STEP)
  • 3D model files: mbr1040ct-etched.step / mbr1040ct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mbr1040ct.step / mbr1040ct.glb are the bare package body.
