How much would it hurt if a 2n3904

(1/3) > >>

lordvader88:
For example if u hold a small TO-92 2N3904 in your fingers, and feed it enough current to explode it, or enough voltage, etc how bad would that be if u hold it ?

With say under 30V 10A, a typical bench supply. I don't plan on doing this, just wondering.

I suppose I could test it a bomb calimeter, or on test materials, but that would take a lot more effort. All tho it would be fun, IDK...

jmelson:
I can tell you!  It will hurt plenty, for several days at least.  The 300 W you mention will not explode the part, it will just get extremely hot.  It probably takes several KW, for a few ms, to actually explode even a tiny transistor.  I have made the mistake of grabbing parts to see if any were getting hot, and then regretted it!

Please wear eye protection. But limbs are somewhat replaceable. The explosion will send shrapnel few meters max, so you will survive

edit: you will be inhaling purest silicon vapor possible, may be with traces of silan and unique organic copper composites yet unknown to general public. Tell us what superhuman side effects will follow the experiment

Ian.M:
If you pump kiloamps through it to explosively vaporise the die and bond wires, I'd bet on severe burns to your hand with maybe enough energy in the explosion to take part of a finger or two off.  At lower currents the odds are it will get red hot long before it explodes, so the damage would depend on how long you are dumb enough to hold it for.

If you want to experiment, you'll need some sort of high energy capacitor discharge rig, and a polycarbonate or other impact resistant plastic blast shield.

lordvader88:
OK not something to do any time soon in my bedroom. Yeah and checking transistor temp's by touch, do at own risk everytime.

What about with a 9V battery blowing up a little transistor ?
