Dear all,

Given the success in the last thread on transistors, I thought I would ask about SMT variants of the venerable 1N4148 diode.

I got as far as the MMSD4148, but I suspect there are other "common" old-school diodes that have been converted to SMT.

So, what other cheap-as-chips SMT small signal diodes are really common?

I know, .... have a bunch of the mini-melf 1N4148 and those are a pain in the butt to handle: a glass cylinder like the PTH ones, but with no leads. Waaahaaaa ! Ditto for the 1N400x. Not sure if I already have an alternative (not in the shack now), but for signals I use BAR43 schottky's. With the low Vcc's in these days a good choice IMO. And for the 1N400x I use SS14 or SS24 schottky's.

... there is also the 1N4148W in a SOD123 package, and the 1N4148WS in the SOD232 and 1N4148WT in the SOD523 package.

When I went looking for a replacement for the 1N4148, I found http://www.vishay.com/docs/88586/es1.pdf as a likely candidate.

I knew I had to have some .... was just a matter of finding ;)
BAS16 is a nice smd replacement for a 1N4148

Thanks for that :)

Keep suggestions coming for any googlers that might arrive here.

I usually use BAV99 as they are dual in a SOT23 package and cost no more than a BAS16.
