WebMOSFETs only switch current flowing in one direction; they have a diode between source and drain in the other direction (in other words, if the drain (on an N-channel device) falls below the voltage on the source, current will flow from the source to the drain). WebPerformance of MOSFETs: Drain Current and Power Dissipation. Permissible loss and drain current, which are typical maximum ratings of MOSFET, are calculated as follows. (A different expression of current is adopted for some products.) Power dissipation is calculated by thermal resistance and channel temperature.

WebThis is the resistance between the drain-source when MOSFET is on at the specified gate-voltage. The on-resistor R DS (ON) is calculated by dividing the specified drain current ID by the drain current ID, increasing VGS to the specified voltage, measuring the drain-to-source voltage, and calculating the on-resistor.

WebAt V gs Web5 de fev. de 2024 · The drain current is the maximum continuous current the device can conduct. Note that this value is usually spec'd at 25 deg C case temperature, which is normally hard to maintain. It should be regarded more as a figure of merit rather than a realistic maximum current for the device.

WebDrain current is calculated by the calculated power dissipation and ON resistance, using Ohm’s law.

If your load is on with only 25nA, then you might have trouble turning it off. Also, when you turn the MOSFET off, its parasitic capacitances still exist. So, if Vgs=0 from the MOSFET driver, you still have Cgd+Cds …

WebWhen a channel exists in a MOSFET, current can flow from drain to source or from source to drain - it's a function of how the device is connected in the circuit. The conduction channel has no intrinsic polarity - it's kind of like a resistor in that regard. The intrinsic body diode inside the MOSFET is in parallel with the conduction channel ...

WebSignificant gate-induced drain leakage current can be detected in thin gate oxide MOSFETs at drain voltages much lower than the junction breakdown voltage.
