Transient Voltage Suppressor Diode

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.
