P4SMA6.8A

TVS - Diodes

TVS Diode400WSMAUnidirectional

The P4SMA6.8A is a 400W unidirectional TVS diode in an SMA package, providing transient voltage protection for sensitive electronics.

Best for

  • I/O interface protection
  • AC/DC power supply transient protection
  • Signal line protection (RS232, RS485)

Avoid if

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

Check before use

  • Verify the peak pulse power rating against the expected surge energy.
