LUDZS12BT1G

LRC · Zener Diodes · SOD-323

LUDZS12BT1G 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 CATHODE passive Cathode terminal, identified by the polarity band on the package; the device is rated for 200 mW power dissipation and junction temperature up to 150 °C.
2 ANODE passive Anode terminal of the Zener diode; the datasheet gives no pin-specific limit for this terminal.

CAD (KiCad official)

  • Symbol: LUDZS12BT1G
  • Footprint: Diode_SMD:D_SOD-323
  • 3D model: SOD-323 (KiCad packages3D, STEP)
  • 3D model files: ludzs12bt1g-etched.step / ludzs12bt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ludzs12bt1g.step / ludzs12bt1g.glb are the bare package body.
