SMBJ40A

TVS - Diodes

TVS Diode600WSMBUnidirectional

The SMBJ40A is a 600W unidirectional TVS diode designed for transient voltage protection in sensitive electronic circuits.

Best for

  • I/O interface protection
  • AC/DC power supply surge protection
  • Signal line protection

Avoid if

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

Check before use

  • Verify the transient energy profile of your circuit against the 600W rating.
