Protection devices: System protection and low capacitance

With technological leadership in transient voltage suppressors (TVS), ST offers a broad range of solutions, from discrete clamping (Transil™) and crowbar diodes (Trisil™), to ESD data-line protection arrays and protection ICs for telecom circuits.

Based on its well-proven expertise and long time leadership, STMicroelectronics provides the widest range of solutions to secure multiple applications and ports by offering scalability and decentralized protection.


System protection and lower capacitance:

 
protection families
increased miniaturization: extending our ESD protection devices in micro packages
new video and data interface range: enlargement to USB, DVI, HDMI applications
towards higher data rates: lower capacitance to protect without damaging the data signals
