9.2.1 Design Requirements

A typical operation for the TVS1800 would be protecting a 12 V input voltage line with a wide variance requiring extra standoff from the nominal voltage, as shown in Figure 10. In this example, a TVS1800 is protecting the input to an LMZ2005, a power module with an input voltage range of 20 V and an absolute maximum input voltage of 25 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.
