APPLICATIONS INFORMATION
◇ Designed to protect high speed data interfaces
◇ Designed to protect four data lines from transient over-voltages by clamping them to a fixed reference
◇ Designed to protect sensitive components which are connected to data and transmission lines from overvoltage caused by
electrostatic discharge (ESD), electrical fast transients (EFT), and lightning.
◇ TESDS5V0A incorporates eight surge rated, low capacitance steering diodes and a TVS diode in a single package
◇ During transient conditions, the steering diodes direct the transient to either the positive side of the power supply line or to ground
◇ The internal TVS diode prevents over-voltage on the power line, protecting any downstream components

CIRCUIT BOARD LAYOUT RECOMMENDATIONS
◇ To protect data lines and the power line, connect pin 5 directly to the VDD. In this configuration the data lines are referenced to
the supply voltage. The internal TVS diode prevents over-voltage on the supply rail.
◇ The TESDS5V0A can be isolated from the power supply by adding a series resistor between pin 5 and VDD. A value of 100kΩ is
recommended. The internal TVS and steering diodes remain biased, providing the advantage of lower capacitance.
◇ In applications where no positive supply reference is available, or complete supply isolation is desired, the internal TVS may
be used as the reference. In this case, pin 5 is not connected. The steering diodes will begin to conduct when the voltage on
the protected line exceeds the working voltage of the TVS (plus one diode drop).
