SMDJ18A

TVS - Diodes

TVS Diode3000WSMCUnidirectional

The SMDJ18A is a 3000W unidirectional TVS diode in an SMC package, designed to protect sensitive electronics from voltage transients.

Best for

  • Voltage transient protection
  • Surge suppression in industrial and consumer electronics

Avoid if

  • Application requires bidirectional protection (use SMDJ18CA instead)

Check before use

  • Verify the 10x1000us waveform compatibility with your specific transient event.
