SMAJ43AQ-13-F

Diodes Incorporated · ESD And Surge Protection (TVS/ESD) · SMA

SMAJ43AQ-13-F from Diodes Incorporated, 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 terminal, marked by the cathode band on uni-directional devices such as the SMAJ43AQ (VRWM 43V, VBR 47.8V to 52.8V, max VC 69.4V at 5.7A IPP).
2 A passive Anode terminal, the end opposite the cathode band, which connects to the protected ground or return side of the line.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin • Terminals: Lead-Free Plating (Matte Tin Finish). Solderable per MIL-STD-202, Method 208 1

CAD (KiCad official)

  • Symbol: SMAJ43AQ-13-F
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj43aq-13-f-etched.step / smaj43aq-13-f-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj43aq-13-f.step / smaj43aq-13-f.glb are the bare package body.
