Circuit Protection

TVS Diode1500W12VUnidirectional

The SMCJ12A is a 1500W unidirectional TVS diode in an SMC package, ideal for protecting sensitive electronics from voltage transients.

Best for

  • I/O interfaces
  • AC/DC power supplies
  • Signal line protection

Avoid if

  • Applications requiring bidirectional protection (use the CA suffix version instead)

Check before use

  • Ensure the 1500W power rating is sufficient for the expected transient energy.
