TVS diodes are passive components that clamp voltage at a fixed level. Surge suppression ICs are active devices that can disconnect the load, provide current limiting, and offer diagnostic feedback.

Active protection for sensitive downstream electronics
What are Surge Suppression ICs components?
Surge suppression ICs provide active, high-speed protection against voltage transients and overcurrent conditions. Unlike passive TVS diodes, these ICs offer precise threshold control, fast response times, and integrated features like thermal shutdown and fault flagging.
How to Choose Surge Suppression ICs Components
Select based on the specific transient environment and the sensitivity of the load.
Operating Voltage Range
Ensure the IC's maximum input voltage exceeds your system's peak transient levels.
Response Time
Prioritize nanosecond-level response for high-speed data lines or sensitive CMOS inputs.
Integrated Features
Look for built-in thermal shutdown, current limiting, and fault output flags for system diagnostics.
Package Thermal Profile
Verify the thermal resistance of the package to handle power dissipation during a surge event.
Leakage Current
Check quiescent current if the IC is used in battery-powered or low-power standby applications.
