2N5457 MMBF5457 Uses Other Than Pedals

[Bio77]

For some of you EE professionals out there.  I was wondering if the 5457 JFETs are widely used in other industries?  Basically, are the shortage we're seeing now a temporary supply-chain issue or are these going to be rare from now on.

I'm no EE, but I thought I'd read OnSemi made even the SMD MMBF5457s obsolete and discontinued them at the beginning of last year. Which doesn't exactly answer your "what are they used for" question, but I don't think we'll be seeing them come back, supply chain woes or not.

That was actually what I was driving at.  Thanks for the info. 

I knew the TO-92s were gone but I thought the SMDs were going to be around for awhile.
