SMAJ9.0A product

SMAJ9.0A

Transient Voltage Suppressors (TVS)

TVS Diode400WSMAUnidirectional

The SMAJ9.0A is a 400W unidirectional TVS diode designed for transient voltage protection in compact electronic circuits.

Best for

  • I/O interface protection
  • AC/DC power supply transient protection
  • Signal line protection (RS232/RS485)

Avoid if

  • Applications requiring bidirectional protection
  • Surge environments exceeding 400W peak pulse power

Check before use

  • Verify the maximum clamping voltage is within the safe operating range of downstream components.
