S-LMSZ5238BT1G

LRC · Zener Diodes · SOD-123

S-LMSZ5238BT1G from LRC, in a SOD-123. 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, marked by the polarity band on the SOD-123 package; the datasheet specifies the cathode as pin 1 (Style 1).
2 ANODE passive Anode, the pin opposite the cathode polarity band on the SOD-123 package; the datasheet specifies the anode as pin 2 (Style 1).

CAD (KiCad official)

  • Symbol: S-LMSZ5238BT1G
  • Footprint: Diode_SMD:D_SOD-123F
  • 3D model: SOD-123 (KiCad packages3D, STEP)
  • 3D model files: s-lmsz5238bt1g-etched.step / s-lmsz5238bt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s-lmsz5238bt1g.step / s-lmsz5238bt1g.glb are the bare package body.
