4 / 5 page 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. 1 23 4 GND PROTECTED LINE #1 PROTECTED LINE #2 GND OPTIONAL LOCAL BYPASS CAPACITOR VCC = 5 V Specifications are subject to change without notice. The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time. Users should verify actual device performance in their specific applications. |
