product advantages
PROSEMI provides a comprehensive range of overvoltage suppression components, including TVS Diodes, Gas Discharge Tubes (GDTs), Thyristor Surge Suppressors, PLEDs, and ESD Protectors.
These components are designed for use in industrial electronics, communication systems, consumer devices, and automotive circuits, where reliable protection from transient voltages is essential.
Each suppressor is engineered to limit transient overvoltages while maintaining minimal impact on normal circuit operation.
By combining semiconductor and gas discharge technologies, PROSEMI ensures precise clamping characteristics, fast response time, and repeatable performance.
The design process focuses on achieving a balance between surge energy absorption and long-term electrical stability.
All PROSEMI products are manufactured under strict process control and verified by surge pulse, thermal cycling, and high-temperature storage tests.
Advanced metal and ceramic sealing processes help maintain structural integrity and prevent performance degradation over time.
Every batch undergoes statistical sampling and parameter verification to ensure consistency, reliability, and compliance with design specifications.
PROSEMI’s overvoltage suppressors are designed to provide predictable and repeatable protection throughout the product’s service life.
Their proven stability under varying temperature and surge conditions makes them suitable for signal line, power line, and interface protection.
We focus on delivering well-characterized, reliable components that support engineers in building safe and durable circuit systems.
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.
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
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.
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.
