SMAJ3.3A

BORN · ESD And Surge Protection (TVS/ESD) · SMA(DO-214AC)

SMAJ3.3A from BORN, in a SMA(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 of the unidirectional SMAJ3.3A, marked by the band on the package, connected to the positive side with a 3.3V reverse stand-off voltage and 4.20V to 6.55V breakdown at 1.0mA.
2 A passive Anode of the unidirectional SMAJ3.3A, the unbanded end, which is the return side and conducts forward with VF of 5.0V max at 25A.

CAD (KiCad official)

  • Symbol: SMAJ3.3A
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: smaj3-3a-etched.step / smaj3-3a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj3-3a.step / smaj3-3a.glb are the bare package body.
