SZ4524

EIC Semicon · Zener Diodes · DO-214AC(SMA)

SZ4524 from EIC Semicon, in a DO-214AC(SMA). 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 end of the SZ4524 zener diode, identified by the color band, with a nominal zener voltage of 24 V at IZT = 20.8 mA.
2 A passive Anode end of the SZ4524 zener diode, opposite the color-banded cathode, with a maximum forward voltage of 1.2 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: SZ4524
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: sz4524-etched.step / sz4524-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sz4524.step / sz4524.glb are the bare package body.
