SZA12A

LRC · Zener Diodes · DO-214AC

SZA12A from LRC, in a DO-214AC. 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; Zener voltage regulator diode (SZA12A: Vz 12V at Izt 21mA, ±5% tolerance).
2 A passive Anode terminal of the Zener diode; steady state power dissipation 1.0W at TL=75°C.

CAD (KiCad official)

  • Symbol: SZA12A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC (KiCad packages3D, STEP)
  • 3D model files: sza12a-etched.step / sza12a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sza12a.step / sza12a.glb are the bare package body.
