PRODUCTION DATA.
A typical operation for the TVS1400 would be protecting in a factory control application, protecting an analog input to an ADC input similar to Figure 10. In this example, two TVS1400’s are in a bidirectional configuration protecting the input to an ADS8689, an ADC with an input voltage range of ±12.288 V and an absolute maximum input voltage range of ±20 V. Without any input protection, if a surge event is caused by lightning, coupling, ringing, or any other fault condition this input voltage will rise to hundreds of volts for multiple microseconds, violating the absolute maximum input voltage and harming the device. An ideal surge protection diode will maximize the useable voltage range while still clamping at a safe level for the system, so TI's Flat-Clamp technology provides the best protection solution.
