Circuit Protection

TVS DiodeBidirectionalSMA PackageCircuit Protection

The SMAJ51CA is a 400W bidirectional TVS diode designed for circuit protection against voltage transients and ESD in surface-mount applications.

Best for

  • I/O interface protection
  • AC/DC power supply protection
  • Signal line protection

Avoid if

  • Applications requiring 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.
