SMAJ6.8CA-JSM

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

SMAJ6.8CA-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 bidirectional (CA-suffix) transient voltage suppressor, listed in the PINNING table for the SMA package; the datasheet gives no separate limit for this pin beyond the 400W peak pulse power and ±ratings of the device.
2 Anode passive Anode terminal of the bidirectional (CA-suffix) transient voltage suppressor, listed in the PINNING table for the SMA package; the datasheet gives no separate limit for this pin beyond the 400W peak pulse power and ±ratings of the device.

CAD (KiCad official)

  • Symbol: SMAJ6.8CA-JSM
  • Footprint: Diode_SMD:D_SMA
  • 3D model: SMA (KiCad packages3D, STEP)
  • 3D model files: smaj6-8ca-jsm-etched.step / smaj6-8ca-jsm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); smaj6-8ca-jsm.step / smaj6-8ca-jsm.glb are the bare package body.
