9.2.1 Design Requirements

A typical operation for the TVS3300 would be protecting an analog output module on a PLC similar to Figure 10. In this example, the TVS3300 is protecting a 4-20 mA transmitter that uses the XTR115, a standard transmitter that has a nominal voltage of 24 V and a maximum input voltage of 40 V. Most industrial interfaces such as this require protection against ±1 kV surge test through a 42-Ω coupling resistor and a 0.5 µF capacitor, equaling roughly 24 A of surge current. 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, TI's Flat-Clamp technology provides the best protection solution.
