SMBJ40A product

SMBJ40A

TVS - Diodes

TVS Diode600WSMBUnidirectional

The SMBJ40A is a 600W unidirectional TVS diode in an SMB package, designed for effective voltage transient and surge protection in electronic circuits.

Best for

  • General surge protection
  • Voltage transient suppression

Avoid if

  • Bidirectional protection is required (this is a unidirectional device)

Check before use

  • Verify the peak pulse current and clamping voltage match the circuit's transient energy requirements.
