USB Type-C™ Protection

Semtech USB Type-C™ Protection devices help to safeguard individual lines for USB Type-C interfaces. USB Type-C standards are quickly emerging as critical data buses across various electronic equipment. Semtech's RClamp low-clamping voltage, low-capacitance ESD protection solutions safeguard USB type C ports without compromising the signal integrity of the data link. The RClamp solutions protect high-speed data ports, which are extremely sensitive to damage and latch-up from electrostatic discharge, electrical fast transients, and cable discharge threats.
