SZA24A

LRC · Zener Diodes · DO-214AC(SMA)

SZA24A from LRC, 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, marked by the color band on the DO-214AC body; connects to the positive side in zener regulation (Vz 24V at Izt 10.5mA for the SZA24A).
2 A passive Anode of the zener diode, the terminal opposite the color band on the DO-214AC molded plastic package.

CAD (KiCad official)

  • Symbol: SZA24A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: sza24a-etched.step / sza24a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sza24a.step / sza24a.glb are the bare package body.
