Application Scenarios & Design Considerations

High Power Density Surface Mount TRANSZORB? Transient Voltage Suppressors

Alternative Part Number

  • 1SMB28CAT3G --: Same SMB (DO-214AA) package, 28V bidirectional TVS with 400W peak pulse power, directly interchangeable for transient protection.
  • P6SMB28CA --: 600W bidirectional TVS in SMB package with 28V standoff voltage, provides equal or higher surge capability and is a common drop-in replacement.
  • SMAJ28CA --: Bidirectional 28V TVS in SMA package with 400W rating; slightly smaller footprint but electrically compatible for most clamping applications.
