ESD401EVM, standing for ESD Protection Switch Evaluation Module, is a dedicated evaluation and demonstration board, which is classified under the category of Evaluation and Demonstration Boards and Kits. This module is designed by Texas Instruments for evaluation and testing of D-Type ESD Protection Switches.

The application field of ESD401EVM is mainly on the detect and identify the electrostatic discharge (ESD) events on the data lines to the device. It provides the means of measuring and evaluating the ESD characteristics of field-effect transistors (FETs) in terms of their rated peak ESD current, ESD performance, and power handling capability, and provides insight into their implementation of ESD protection in the system.

ESD401EVM also can evaluate and adjust other ESD protection solutions, such as Gas Discharge Tubes (GDTs), Varistors (VARs), and diode arrays, accurately in the lab setting. Investigating the performance behavior from protecting from the ESD event is also possible with this module.

The operation principle of ESD401EVM is basically based on the two-line differential-mode testing. By applying a voltage of the same polarity on the two lines, a positive current will flow from one line to the other, and the measurement of this current is how the module is able to detect and identify the ESD event. This two-line differential approach provides a reliable testing of the protection devices, ensuring accurate results for all measurement tests.

Other useful functions of this module include S-parameter measurements for DSA networks, such as impedance, return loss, isolation, and frequency response. It is capable of performing multiple tests to various power levels and ESD voltage. This module can also be used to measure the response of the protection device to over-voltage.

ESD401EVM is a highly effective module for measuring the characteristics of ESD protection solutions as well as to evaluate the performance of Over-Voltage and Electrostatic Discharge affect. This module can be seen as a powerful tool for companies and organizations who are looking to develop an efficient and comprehensive ESD protection system for their devices.
