It provides \u00b130kV IEC ESD protection for high-speed data lines such as USB, HDMI, and Ethernet without degrading signal integrity. The 0.8pF capacitance makes it transparent to signals up to several GHz.","working_principle":"The PESD5V0S1BAQ uses a bidirectional SCR\/thyristor structure that provides symmetric clamping for both positive and negative transients. Under normal operation (below 5.0V), the device presents extremely low capacitance (0.8pF) and leakage (0.1uA), making it transparent to high-speed signals. When an ESD event exceeds the breakdown voltage, the device rapidly avalanches and clamps the voltage, diverting the ESD current away from the protected IC. The ultra-low capacitance is achieved through specialized junction design optimized for high-frequency signal integrity.","pin_description":"
