CD143A-SR05LC - Steering/TVS Diode Array Series
Application Information
The Model CD143A-SR05LC is designed to protect two data lines
against transient overvoltage events, as well as to limit the transient
voltage on the 5 V supply line of the protected device.
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).
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.
