most sensitive circuit elements?

(1/2) > >>

coppercone2:
What is the most sensitive circuit element that you can think of in terms of being able to handle some kind of power ?

I know bare signal FETs are very sensitive to ESD, but I mean in a properly hooked up system that has a generator of some sort connected to it giving it a steady state signal that slowly rises.

Alex Eisenhut:
Not sure exactly what you're driving at here but mixer/sampling diodes are pretty easy to blow.

T3sl4co1l:
Easy: a transistor, in the smallest possible feature size (a few nm across?), in the lowest melting point semiconductor that's still capable of transisting at room temperature say.

I wonder what the ratings of superconducting elements are (Josephson junctions and whatnot)?

coppercone2:
what manufactured commercially used device comes closest? like, a component with a input, not something buried inside of a CPU thats inaccessible by any reasonable means.

is there some notorious transistor family etc?

Gyro:
This is a ridiculous question without knowing what circuit the element is used in. Sensitive parts may well be well protected by surrounding components (even resistor choices). In a properly designed circuit any part may fail before the 'most sensitive' one.

It's impossible to say without any context!
