The ESD56161D05-3/TR is an Electrostatic Discharge (ESD) protection diode with TVS DFN2x2-3L RoHS packaging manufactured by Will Semiconductor. It features low capacitance and low clamping voltage and stands up to 25kV of ESD. The ESD56161D05-3/TR is made with a dual N-Channel trench technology and a built-in ESD protection in a small 2 mm x 2 mm optional DFN package that fits through hole SMT pads. It is ideal for use in portable electronics, such as phones, tablets, and laptops, where space is at a premium but ESD protection must still be provided.
