Matt,

An SCR doesn't turn off until the current falls below a small value (I think
it's called holding current).  The MOSFET (enhancement mode) turns off when
the gate drive goes to zero.

I remember seeing some type of SCR that could be turned off by driving the
gate, but I haven't investigated them..

Hi all, i am wondering if an SCR would work as well as a MOSFET?Since these
MOSFETs have SO many ways to die, maybe an SCR would do better?I have some
big SCRs.Studs and hockey puck types.So they can take WAY more than a
MOSFET.And all i got to worry about is CEMF.Is there any reason why it
shouldnt work?

Thanks,
Matt
