Another cause of conducted EMI is the ground planewhere fast switching currents induce voltage spikes.
The logic inputs are protected against voltage spikes up to +14V, regardless of VDD voltage. .
The value of this resulting capacitor will be three times thevalue of the parasitic capacitance that is creating the voltage spikes.
This application note describes how to suppress the voltage spikes with a simple resistor-capacitor(RC) network.
If the voltage spikes are higher than the MOSFET's voltage tolerance, a snubber circuit will be necessary to dissipate the leakage energy.
The MAX5953A provides the following features:TVS diode D1 protects against transient voltage spikes and against reverse-voltage application.
Because the voltage generated is proportional to the change in the magnetic field with time(dΨ/dt),these rapid field fluctuations can generate large voltage spikes.
In a real system, if you chop off inductive currents,you will see voltage spikes across the inductors, which likely will damage your circuit.

Voltage spikes appear on the drain of the n-channel power MOSFET when the gate of the MOSFET is turned off and also when the gate of the complimentary MOSFET is turned on.
Signal Line Protection ICs- Maxim Crosstalk, electromagnetic interference(EMI), and electrostatic discharge(ESD)can cause voltage spikes that destroy input circuitry.
Safety Device Diagnostics"provides data such as partial operation, voltage spikes and dips, temperature effects, switching cycles, bounce and RFID identification as diagnostic information.
Not only do high-current loops radiate magnetic fields, but they also increase the inductance of conductors,which can cause voltage spikes on lines that carry high-frequency current.
The MAX4936/MAX4937 featureclamping diodes to protect the receiver input from voltage spikes due to leakage currents flowing through the T/R switches during transmission.
In a push-pull drive scheme, the parasitic inductance of the step-up transformer, together with the parasitic capacitance of the output of the n-channel power MOSFETs,form a resonant circuit that can create unwanted voltage spikes.
In actual inputs, however, not only is there ripple due to the on-off switching of the input current,there are also voltage spikes and noise, caused by high-frequency current transitions that accompany switching.
Example of How to Determine the Proper RC Snubber Values In this section, using the five-step procedure outlined previously, the proper values for the resistor(R) and capacitor(C)snubber circuit to reduce the Figure 1 voltage spikes are determined.
