High dv/dt
WebIt can be noted that in figure 6 the dV/dt and tail current losses are around the same with a gate resistance of 47 Ω. Even though the tail current is constant, the losses in a system are often predominantly due to dV/dt, because the value of the gate resistance is often too high. In the example of figure 7, the total losses per WebThis power MOSFET is usually used at high efficient DC to DC. converter block and SMPS. It’s typical application is TV and monitor.

WebThese are trigger voltage and current, holding current and dV/dt. The basic properties of silicon are the same for thyristors as for ordinary diodes. However, the thyristor construction is a p-n-p-n sandwich between its main terminals, so the forward voltage drop is higher than that of an ordinary diode, generally from 0.8 to 2 V depending on current.
