This part is used in our SparkFun Inventor's Kit as a flyback diode to prevent voltage spikes. For more information, try looking at some of the examples linked below that use this diode:
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

You know you have a good supplier if they not only admit they're not the cheapest, but also point you to who is cheaper. I appreciate the complete honesty, Sparkfun!
you know what because of that complete honesty from Sparkfun im going to not order from digi but order from Sparkfun!
The SMT equivalent is LL4148, unfortunately in the not so practical MELF package. (MELF = Many End up Lying on the Floor)
Maybe the most heavily stocked item on SparkFun :P
That's funny because it's currently out of stock and there is no ETA.
what part in the Sparkfun Eagle library should I use?
Eagle comes with a number of standard libraries with thousands of parts; there's a 1N4148 in the DIODES library. You can search through the active libraries by using wildcards ("*") in the part name.
