SMC5343A

ZHIDE · Zener Diodes · DO-214AB(SMC)

SMC5343A from ZHIDE, in a DO-214AB(SMC). 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 by the color band; the 7.5 V (7.13 to 7.88 V) zener is reverse biased with this pin positive.
2 A passive Anode, the end opposite the color band; maximum forward voltage is 1.2 V at 200 mA.

CAD (KiCad official)

  • Symbol: SMC5343A
  • Footprint: Diode_SMD:D_SMC
  • 3D model: DO-214AB(SMC) (KiCad packages3D, STEP)
  • 3D model files: smc5343a-etched.step / smc5343a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smc5343a.step / smc5343a.glb are the bare package body.
