Gate drain breakdown voltage
WebThe voltage drop across the drain source terminals of a MOSFET is a linear function of the current flowing in the semiconductor. This linear relationship is characterized by the RDS(on)of the MOSFET and known as the on-resistance. On-resistance is constant for a given gate-to-source voltage and temperature of the device. WebApr 11, 2024 · In many hard switching (HSW) power conversion applications, the parasitic gate loop inductance, Miller feedback from the drain switching, or crosstalk between signal and power paths can result in substantial V GS overshoots. Quantifying the dynamic gate breakdown voltage can help evaluate the transient single-event gate overshoot limits …
