8 Application and Implementation

Note

Information in the following applications sections is not part of the TI component specification,

and TI does not warrant its accuracy or completeness. TI’s customers are responsible for

determining suitability of components for their purposes, as well as validating and testing their design

implementation to confirm system functionality.

8.1 Application Information

The ESD1LIN24-Q1, ESD751-Q1, and ESD761-Q1 are single channel TVS diodes which are used to provide

a path to ground for dissipating ESD events on LIN signal lines. The LIN signal lines are typically routed

throughout the automobile to connect between the different ECUs. As the current from ESD passes through the

TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC.

The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a safe level for the protected IC.
