The ESD9R is designed to provide ESD protection for ASSPs and ASICs used in ultra low current applications such as human body sensors. These devices have been designed for leakage under 1nA from 0C to 50C when turned off. During an ESD event, these devices turn in to clamp the ESD to a safe voltage level for the IC. These devices have the added benefits of low capacitance for high speed data lines and small package size for space constrained designs.
