Paulo has developed a free RC snubber calculator, an Excel-based calculator 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.
The most common way to mitigate the effects of these transients is by using an RC snubber circuit. There are many excellent sources on the web discussing this topic so I won’t repeat the discussion here (see references below for more information). Instead, I’m offering an Excel-based calculator that simplifies the components selection should you be faced with this task.
