What does the Ifsm rating of an scr mean?
What does the Ifsm rating of an scar mean?

** I = current, f = forward, s = single, m = maximum.
Generally it refers to the largest, once in a while, *half cycle 50/60 Hz
* current pulse allowable.

So I have a power supply that has a zener diode across the output to
trigger an SCR in the event of over voltage.......
The power supply's fuse is , say 10 amp. Does the SCR's rating have to be
at least 10 amp or will a lower rating one do given that the fuse in the
event of a short to ground through the SCR will fail pretty quickly
Yeah OK, but what's with the piss off bit?Post the full schematic and all the details an ABSE.
Or else piss off .
Yeah OK, but what's with the piss off bit?
** Cos YOU are bloody TROLLING !!!!!

The power supply in question is a Johnson Unit that I've repaired for a
friend.

The semiconductors only had in house type numbers on them.
My p was a genuine question. What seems elementary to you is not to me.
Peter Howard said:Peter,
Is that Phil Allison you are having a discussion with?
If so, you are wasting your time trying to reason with him. Just killfile
the graceless prick. I did, six months ago and have not missed him.
His technical knowledge is quite good but he turns to psychotic abuse for
no reason. Or maybe his reason is the gratification of getting a shocked
reaction. Whatever. He is a troll and is not worth your trouble.

Yeah, good advice.

Is there some unwritten rule about posting to this NG that I've missed
somewhere?

(wink wink) so best if you're thin skinned to push it over in the wanker
file to be ignored.

individual.
