To optimize the performance of the protection design, connections to the CD143A-SR05LC should be as short as possible. This will minimize the parasitic inductance of the printed circuit board traces. An optional 0.1 μF bypass chip capacitor can be added from Pin 4 to Ground to enhance the ESD performance of the design when the nearest bypass capacitor is a significant distance from the Model CD143A-SR05LC. Pin 1 must be connected to the local Ground used by the protected device and Pin 4 must be connected to the 5 V supply rail used by the protected device, as shown in the figure below. Under no circumstances should Pins 1 and 4 be left unconnected (floating).
