[Amps] MRFE6VP Datasheet

[alexeban]

Hi everybody:
FET's , per se, don't have any intrinsic time related effects.
On the other hand a CW wave is actually a 50% square wave, producing in
effect a 50% duty cycle.
This might indicate that some duty cycle limitation can exist for greater
than 50% situations. It was usually present on IRF switching power supply
devices, years back. you could actually melt the internal bonds when
operating them at maximum current for prolonged periods, especially the
source bonds.

I have not looked very close at the data sheet but it did occur to me that 
in some applications some devices require time to thermally or electrically
stabalize.
But, you may be right. I'll look closer.

I think the pulse operation applies to the 60:1 VSWR specification.
Effectively, that gives a specification on how fast the control circuit need
to
operate.
