While they look similar, TVS diodes are optimized for high-power transient suppression with faster response times, whereas Zener diodes are designed for voltage regulation.
TVS - Diodes Component Intelligence
Precision voltage clamping for transient surge protection.
What are TVS - Diodes components?
TVS diodes are semiconductor devices designed to protect sensitive circuits from voltage spikes by clamping excess energy to a safe level. They are essential for ESD and surge protection in data lines, power rails, and automotive interfaces.
How to Choose TVS - Diodes Components
Selecting the right TVS diode requires balancing clamping speed, energy handling, and signal integrity.
Standoff Voltage (Vrwm)
Must be equal to or greater than the maximum operating voltage of the circuit to prevent leakage.
Clamping Voltage (Vc)
The maximum voltage the diode allows during a surge; ensure this is below the damage threshold of your protected IC.
Peak Pulse Power (Ppp)
Determines the diode's ability to handle transient energy; match this to your expected surge profile.
Capacitance
Critical for high-speed data lines; choose low-capacitance parts to avoid signal distortion.
Unidirectional vs Bidirectional
Use unidirectional for DC rails and bidirectional for AC or differential signal lines.
