MMBD301LT1G

onsemi · Schottky Diodes · SOT-23

MMBD301LT1G from onsemi, 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 the Schottky hot-carrier diode; the device is rated for 30 V reverse voltage (VR) and 200 mA maximum DC forward current.
2 NC unconnected No connection; this pin is not internally connected on the SOT-23 package.
3 CATHODE passive Cathode terminal of the Schottky hot-carrier diode; the device is rated for 30 V reverse voltage (VR) and 200 mA maximum DC forward current.

CAD (KiCad official)

  • Symbol: MMBD301LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbd301lt1g-etched.step / mmbd301lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbd301lt1g.step / mmbd301lt1g.glb are the bare package body.
