MMBD354LT1G

onsemi · Schottky Diodes · SOT-23

MMBD354LT1G 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 of one diode in the dual pair; the datasheet gives a continuous reverse voltage of 7.0 V per diode and a forward voltage of 0.60 V max at IF = 10 mAdc.
2 ANODE passive Anode of the second diode in the dual pair; the datasheet gives a continuous reverse voltage of 7.0 V per diode and a forward voltage of 0.60 V max at IF = 10 mAdc.
3 CATHODE passive Common cathode shared by both diodes; the datasheet gives a capacitance of 1.0 pF max at VR = 0 V, f = 1.0 MHz per diode.

CAD (KiCad official)

  • Symbol: MMBD354LT1G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbd354lt1g-etched.step / mmbd354lt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbd354lt1g.step / mmbd354lt1g.glb are the bare package body.
