Paulo has developed an Excel-based calculator that eases the design of RC snubbers in power switching applications:
In power switching applications, a designer often has to contend with spurious oscillations. These are the result of parasitic capacitances and inductance on the board and behave like the step response of an RLC circuit. These transients can induced undesired noise in neighboring circuits and create over voltage spikes that can compromise long term component reliability.
