SMAJ26A-JSM

JSMSEMI · ESD And Surge Protection (TVS/ESD) · SMA

SMAJ26A-JSM from JSMSEMI, 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 Cathode passive Cathode terminal of the unidirectional TVS diode; the device is rated for 400 W peak pulse power at a 10/1000 µs waveform.
2 Anode passive Anode terminal of the unidirectional TVS diode; the device is rated for 400 W peak pulse power at a 10/1000 µs waveform.

CAD (KiCad official)

  • Symbol: SMAJ26A-JSM
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj26a-jsm-etched.step / smaj26a-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj26a-jsm.step / smaj26a-jsm.glb are the bare package body.
