ESD protection diode

Selecting the right electrostatic discharge (ESD) protection for high-speed data lines requires balancing clamping performance with minimal signal degradation. Low capacitance ESD diodes have become essential components in applications ranging from USB-C and HDMI interfaces to automotive communication buses and industrial control systems. Key Takeaways Low-capacitance ESD diodes keep high-speed signal integrity intact while clamping … Read more

A USB ESD protection diode is a TVS device placed in parallel with USB data and power lines to clamp an electrostatic discharge transient within nanoseconds, before it can damage the controller or PHY downstream. The selection is dominated by two numbers that pull in opposite directions: the working voltage must sit above the bus, … Read more
