Hi.
I was primarily looking at the small 0.9 and 1.2 A
variants in 8-pin DIP cases. The PR3-series.
Digikey have them for $0.95 in quantity of 50 for
a chip with an integrated Triac and opto coupler
220V and 1.2A. See : http://dkc3.digikey.com/PDF/T031/0854.pdf
I'm specificaly interested in the PR3BMF11NSZ.

Anyway, Digikey sharges a bit to much for over-seas distribution,
so I'd not like to order just a few from them just for tests.
They want $5 for "Handling", $6 for "Intl. processing fee" and
an "unknown" amount for p&p...

I looked at the Opto22 devices, most of them was the "Zero crossing"
variant, which, if I'm not misstaken, make them unusable for
lamp dimmer applications.

Anyway, my design already uses a separate opto coupler ("Triac trigger")
and a standard Triac. I just thought I'd might get fewer parts...

Thanks anyway !

Jan-Erik.
