diode change

I'm building a picmicro programmer, and I'm fcollowing the schematics from this from sparkfun

they want a BZV55C5V1 diode, but the closest thing that I could find on mouser was a BZX55C5V1 diode

here's the link for the BZV55C5V1 datasheet, just click one, they're all the same

Should work fine. I *think* the main difference is that the BZV diode is SMT, while the BZX diode is leaded.

(although, this is a traditional problem with building your own programmer. You build your programmer, write your first program, click the download button and if it doesn't work, you have no idea whether the problem is in your program, your programmer, your programmer software, your choice of components, the published schematics, ...)

that's a fear, but I just got 50 dollars for christmas form my great aunt and uncle, was going to buy the programmer, but then thought=, why spend 14 dollars + shipping, or pay 2 dollars somewhere else that you're already going to buy from?
one way to avoid some of the headaches is to try a "tried and true" program first, one you know can't fail, that way you know where the problem lies if you have a problem. And if not, its time to dance ! LOL

Yeah, that's what it looks like.

It's a Zener diode, so the main parameters to look for are its breakdown voltage (Zener Voltage Vz = 4.8-5.4V) and its power rating (500mW). If you match those, you should be fine for *most* applications.

Thanks guys!
