SMAJ18CA

TVS - Diodes

TVS DiodeBidirectional400WSMA

The SMAJ18CA is a 400W bidirectional TVS diode used for transient voltage protection in sensitive electronic circuits.

Best for

  • I/O interface protection
  • AC/DC power supply regulation
  • RS232/RS485 signal line protection

Avoid if

  • The application requires higher than 400W peak pulse power dissipation.

Check before use

  • Verify the transient energy levels in your circuit to ensure they do not exceed the 400W rating.
