LM3Z47VT1G

LRC · Zener Diodes · SOD-323

LM3Z47VT1G from LRC, in a SOD-323. 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, indicated by the polarity band; the 47 V nominal Zener (44 V min to 50 V max at IZT = 2 mA) breakdown is a reverse voltage with this pin positive relative to the anode.
2 A passive Anode; forward voltage is 0.9 V max at IF = 10 mA for all types.

CAD (KiCad official)

  • Symbol: LM3Z47VT1G
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: lm3z47vt1g-etched.step / lm3z47vt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm3z47vt1g.step / lm3z47vt1g.glb are the bare package body.
