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.
The PROSEMI Transient Voltage Suppressor (TVS) Diode is designed to protect sensitive electronic components from voltage spikes and transient surges. By clamping high voltage levels to a safe range, these diodes prevent damage from electrostatic discharge (ESD), lightning strikes, and other sudden voltage fluctuations that can occur in power lines or communication networks.
Ideal for a wide range of applications, including consumer electronics, automotive circuits, telecommunications, and industrial systems, the PROSEMI TVS Diode ensures the longevity and reliability of your devices by offering fast response times and excellent energy absorption capacity.
With a variety of voltage ratings and configurations available, the PROSEMI TVS Diode provides effective and cost-efficient protection, safeguarding your circuits from potentially damaging transients while maintaining optimal performance.
