Our product range includes solutions suitable for a wide array of applications—from residential and commercial systems to industrial and high-tech environments. Compatible with various devices, they ensure seamless integration with minimal hassle.
PROSEMI Transient Voltage Suppression (TVS) Diodes are designed to protect sensitive electronic components from voltage spikes and transient surges. By clamping high voltages to a safe level, these diodes prevent damage caused by electrostatic discharge (ESD), lightning strikes, and other sudden voltage fluctuations that may occur in power lines or communication networks.
PROSEMI TVS Diodes are suitable for a wide range of applications, including consumer electronics, automotive circuits, telecommunications, and industrial systems. With fast response time and excellent energy absorption capability, they ensure long-term reliability and durability of electronic devices.
Available in various voltage ratings and package configurations, PROSEMI TVS Diodes provide effective and cost-efficient protection for your circuits—maintaining optimal performance while preventing potential transient damage.
Suppressor diodes (also known as TVS diodes) provide fast protection against transient voltage spikes by clamping high voltages to safe levels within nanoseconds. They feature low clamping voltage, high surge capability, and quick response, offering reliable protection for automotive electronics, power supplies, communication equipment, and industrial control systems.
