TVS - Diodes

TVS Diode600WBidirectionalSMB

The SMBJ30CA is a 600W bidirectional TVS diode designed for robust circuit protection against voltage transients.

Best for

  • Data line protection
  • LAN interfaces
  • General voltage transient suppression

Avoid if

  • Applications requiring higher than 600W peak power dissipation

Check before use

  • Verify the peak pulse current (IPP) and clamping voltage (VC) match your specific transient event profile.
