dV/dt is the amount of voltage change per unit time. The steeper the rising slope of VDS, the more likely it is that the dV/dt failure of the MOSFET will occur.
dV/dt failure is a phenomenon in which the charging current flowing through the parasitic capacitance Cds flows through the base resistor RB when the MOSFET is turned off, causing the parasitic bipolar transistor to conduct, causing a short circuit and causing failure.
Generally speaking, the worse the reverse recovery characteristics are and the steeper the dV/dt slope is, the easier it is to cause MOSFET dV/dt failure.
