SZ455G

LGE · Zener Diodes · DO-214AC(SMA)

SZ455G from LGE, 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, the end marked with a color band; the 5.6 V nominal Zener (VZ at IZT = 89.5 mA) is reverse-biased with this pin positive relative to the anode.
2 A passive Anode, the end opposite the color band; maximum forward voltage is 1.2 V at IF = 200 mA.

CAD (KiCad official)

  • Symbol: SZ455G
  • Footprint: Diode_SMD:D_SMA
  • 3D model: DO-214AC(SMA) (KiCad packages3D, STEP)
  • 3D model files: sz455g-etched.step / sz455g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sz455g.step / sz455g.glb are the bare package body.
