SMBJ40CA product

SMBJ40CA

Transient Voltage Suppressors (TVS)

TVS DiodeBidirectional600WSMB

The SMBJ40CA is a 600W bidirectional TVS diode in an SMB package, designed to protect sensitive circuits from voltage transients.

Best for

  • I/O interface protection
  • AC/DC power supply transient suppression
  • RS232/RS485 signal lines

Avoid if

  • Applications requiring higher than 600W peak pulse power dissipation.

Check before use

  • Verify the transient energy levels in your circuit to ensure they do not exceed the 600W rating.
