TVS - Diodes

TVS Diode400WSMATransient Protection

The SMAJ78A is a 400W surface-mount TVS diode designed for transient voltage protection in electronic circuits, featuring a 78V reverse stand-off voltage.

Best for

  • Voltage transient protection
  • Surge suppression in power lines

Avoid if

  • Applications requiring higher than 400W peak pulse power
  • Bipolar protection requirements (this is a unidirectional device)

Check before use

  • Verify the maximum clamping voltage does not exceed the voltage tolerance of downstream components.
