Most diacs are used for pulse generation, probably in the order of amps, and
are designed as such. I think the published ratings for static (DC) use are
a bit on the consevative side, take a 1N4148 sized diac and say 100 to 200
mW dissipation and about 2V across the diac we are left with 50 to 100 mA,
more than enough!
My question is, Is this web site confused. When I looking up a 1N4148 it is
NOT a Diac, it is a Diode. Please bear with me as I'm a novice. A Diac goes
in one direction and will start conducting electricity at a certain voltage.
I Get that.
A diode works in one direction also but from that point I'm a little unsure
what the difference is. Can anyone explain this in simple terms? Does the
Diode also limt voltage eg. a 5v Diode limits voltage to well .. 5V.
A 1N4148 is a diode. A diac is not a diode.
