Forgive me for this dumb question please but I cannot understand it.
Let's say we have a MOSFET IRF1404. The specs say that it has a VDSS of 40 V, an RDS(on) of 0.004 ohm and a continuous drain current of 202 A!
This MOSFET resides in a TO220 case.
How can it be possible that 202 A current flows through it's contacts?
(Btw. 202 A * 0.004 ohm = 0.808 V and this results in 163 Watts power dissipation. The specs say that it's max. power dissipation is 333 W. On the paper everything seems OK).
What am I missing? How should I interpret the datasheet figures?
Thank you very much.
