- High surge capability.  
- Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.  

This information is based on STMicroelectronics' official datasheet for the SMBJ40CA-TR.

Application Scenarios & Design Considerations

TRANSIL

Alternative Part Number

  • P6SMB43CA --: Bidirectional 600W SMB TVS diode with a comparable standoff voltage, suitable drop-in replacement for general transient protection.
  • SMAJ40CA --: Bidirectional 400W SMB TVS with the same 40V standoff voltage; lower power rating but pin-compatible for less severe surge environments.
  • 1SMB40CA --: Bidirectional 600W SMB TVS diode with matching 40V standoff, offering similar clamping performance in the same package.
