What is drain current in MOSFET?

The drain current below threshold voltage is defined as the subthreshold current and varies exponentially with Vgs. The reciprocal of the slope of the log(Ids) vs. Vgs characteristic is defined as the subthreshold slope, S, and is one of the most critical performance metrics for MOSFETs in logic applications.

How much current can a MOSFET handle?

High amperage MOSFETs like the 511-STP200N3LL say they can handle 120 Amps of current.The Metal Oxide Semiconductor Field Effect Transistor, or MOSFET for short, has an extremely high input gate resistance with the current flowing through the channel between the source and drain being controlled by the gate voltage.
