TVS - Diodes

TVS Diode400WSMAUnidirectional

The SMAJ51A is a 400W unidirectional TVS diode designed for transient voltage protection in surface-mount applications.

Best for

  • Sensitive electronics protection
  • Inductive load switching protection

Avoid if

  • Applications requiring bidirectional protection (use SMAJ51CA instead)

Check before use

  • Verify the peak pulse current and clamping voltage match your transient energy requirements.
