What Is The Difference Between TVS Diodes And GDTS?
TVS diodes react within picoseconds, ideal for protecting ICs and data lines.
GDTs handle higher surge currents but respond slower, making them better for power and telecom line protection.
In many designs, they are used together to provide multi-stage protection.
How Do I Choose The Right Suppressor For My Circuit?
Selection depends on several key factors:
Working voltage of your circuit
Application environment (industrial, telecom, automotive, etc.)
Clamping voltage and response time requirements
Surge energy or current rating expected in the system
What Are The Main Types Of Overvoltage Suppressors?
PROSEMI offers several types:
TVS Diode – Fast response for low-energy transients and signal lines.
Gas Discharge Tube (GDT) – Handles high surge current in communication and power systems.
Thyristor Surge Suppressor (TSS) – Provides precise triggering and low leakage.
PLED / ESD Suppressor / Polymer Suppressor – Used for low-voltage and high-speed data interfaces.
What Is An Overvoltage Suppressor?
An overvoltage suppressor is an electronic protection component designed to limit transient voltage spikes caused by lightning, electrostatic discharge (ESD), or switching surges. It protects sensitive circuits by clamping excessive voltage to a safe level.
