TVS - Diodes

TVS Diode400WSMALittelfuse

The SMAJ400A is a 400W unidirectional TVS diode from Littelfuse, optimized for protecting sensitive circuits against high-voltage transients in a compact SMA package.

Best for

  • I/O interfaces
  • VCC bus protection
  • Telecom equipment

Avoid if

  • Applications requiring bidirectional protection or higher power dissipation than 400W.

Check before use

  • Verify the transient energy levels in your circuit to ensure the 400W rating is sufficient.
