We have provide BZX84-C3V6 and nearly complete series of 0805/1206 SMT capacitor and resistor for e-retail purpose. Hope this help hobbyist!

Just serch for sener and mark the 3.6V SMD versions.
A Mini-MELF package (a.k.a. SOD80), is the standard package for standard SMD zener diodes and easy to find everywhere.
Here's a cheap one from NXP (former Philips Semiconductors), price US$ 0.17: http://search.digikey.com/scripts/DkSea ... -3794-1-ND
But you can also find smaller packages.

If you need a more compact solution you can get dual 3.6V zener diodes in a single SMD package.
For example this 3-pin package with common anode: http://search.digikey.com/scripts/DkSea ... 6-FDICT-ND
Or this even smaller package with 6 pins and two seperate zener diodes inside: http://search.digikey.com/scripts/DkSea ... V6SDICT-ND

I would expect any 5227 to work. The only difference should be the packaging. Just make sure the parameters are as close as possible.

I wanted to help anyone looking to use the 3.6 volt Zener on the D+ and D- lines method of making the interface. I ordered these diodes 1N5227B-T digikey number: 1N5227BDICT-ND. I build the interface and it has worked on a 6 different make and models of computers.
On the surface mount zener question, I was looking for someone that has actually used one and built the interface. I have used their search method and found several that might work.

Like these ? Digikey has a neat component selection tool, just type "zener" into the search bar and go from there..

Has anyone build the USB interface, 3.6 Zener, 68 ohm resistor, 1.5K pullup using SMT parts? If so do you have Digikey part numbers for the Zener diodes?
