Add to Watch List

RClamp®0542ZA is an ultra low capacitance ESD protection device designed to protect two high-speed lines in an 0201 footprint. This revolutionary package design reduces board space requirements by more than 50% over existing single line solutions. RClamp0542ZA is a three pin device with identical low capacitance TVS diodes connected to each pin. Any two pins may be connected to high-speed lines, while the third pin is connected to ground. This gives the designer maximum flexibility in pcb routing. Each line has a maximum capacitance of only 0.30pF resulting in a typical corner frequency of 12GHz.
