WebPD DEVICE TOTAL = PD RESISTIVE + PD SWITCHING. Because a MOSFET's power dissipation depends greatly on its on-resistance, R DS (ON), calculating R DS (ON) seems a good place to start. But a MOSFET's R DS (ON) depends on its junction temperature, T J. In turn, T J depends on both the power dissipated in the MOSFET and the thermal … WebJun 24, 2024 · The CMOS switch chips (e.g. 4066, DG201 and similar) use fets with a separate substrate contact and no reverse diode. So no need for 2 fets in series in this case. Heh, in fact they use two in parallel instead (complementary P and N), to extend the voltage range and get a flatter R(on) vs. Vcm.
