SMBJ43A

TVS - Diodes

TVS Diode600WSMBUnidirectional

The SMBJ43A is a 600W unidirectional TVS diode in an SMB package, suitable for protecting sensitive electronics from voltage surges and ESD.

Best for

  • ESD protection
  • Surge suppression in portable electronics

Avoid if

  • The circuit requires bidirectional protection or higher power dissipation than 600W.

Check before use

  • Verify the peak pulse current and clamping voltage match your transient protection requirements.
