SMA3Z22A

ZHIDE · Zener Diodes · SMA

SMA3Z22A from ZHIDE, in a 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 Zener diode conducts in reverse breakdown at VZ 22.0 V nominal (20.90 to 23.10 V) at IZT 34.0 mA.
2 A passive Anode; maximum forward voltage is 1.2 V at IF=200 mA and DC power dissipation is 3.0 W at TL=75 °C.

CAD (KiCad official)

  • Symbol: SMA3Z22A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: sma3z22a-etched.step / sma3z22a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sma3z22a.step / sma3z22a.glb are the bare package body.
