SMAJ24A-AT

Brightking Elec (TAIWAN) · TVS · SMA(DO-214AC)

SMAJ24A-AT from Brightking Elec (TAIWAN), 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 Cathode passive Cathode terminal, marked by the color band on the unidirectional SMAJ24A-AT, which has VRWM 24.0 V, VBR 26.70~29.50 V at 1 mA and VC 38.9 V at IPP 10.3 A.
2 A passive Anode terminal at the end opposite the cathode band on the unidirectional SMAJ24A-AT, which is rated for 400 W peak pulse power at 10/1000μs.

CAD (KiCad official)

  • Symbol: SMAJ24A-AT
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA(DO-214AC) (KiCad packages3D, STEP)
  • 3D model files: smaj24a-at-etched.step / smaj24a-at-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj24a-at.step / smaj24a-at.glb are the bare package body.
