What does the dv/dt of the MOSFET mean?

The dv/dt of the MOSFET is the changing rate of the drain-source voltage during the switching transient.

If dv/dt is too large, ringing may occur, possibly leading to MOSFET damage.

Therefore, dv/dt ruggedness values are specified for some MOSFETs.

For MOSFET’s ringing, please refer to “Parasitic Oscillation and Ringing of Power MOSFETs:Power MOSFET Application Notes.”
