WebDiode voltage drop vs current The voltage drop across a diode increases with current in a non-linear fashion. But as the differential resistance is less, the increase is very slow. We can consider the forward voltage vs current characteristics. WebMar 10, 2024 · This is because when the FET Vgs voltage is ON, the current flows from drain to source (yes, this works - enhancement FETs conduct in either direction). Because Rds (on) is low, not enough voltage develops to forward-bias the body diode above its threshold, so it doesn't conduct. bullying sexual portugues https://qtproductsdirect.com
