SMAJ7.5A

Transient Voltage Suppressors (TVS)

TVS Diode400WSMAUnidirectional

The SMAJ7.5A 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 lines
  • RS232/RS485 signal lines

Avoid if

  • Applications requiring bidirectional protection (use the CA suffix version instead).

Check before use

  • Verify the maximum transient energy expected in the circuit.
