The ESD9R3.3ST5G is an ultra-low capacitance ESD protection diode created to safeguard ASSPs and ASICs in ultra-low current applications. It operates with a reverse standoff voltage of 3.3 V and features an extremely low leakage current of under 1.0 nA from 0°C to 50°C. Key characteristics include a typical capacitance of 0.5 pF, a minimum breakdown voltage of 4.8 V, and a maximum clamping voltage of 7.8 V at a 1 A peak pulse current. Due to its low capacitance, fast response time, and small SOD-923 package, this device is ideal for protecting high-speed data lines and space-constrained designs like human body sensors.
