Note: Complete Technical Details can be found at the datasheet given at the end of this page. A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above.

Pages: . Suyano Jr. On the Internet, I heard about an analogue of this diode - SS Is it suitable for my purposes? Maybe someone connected this regulator with other diodes? You need to look at the data sheets to see if it's an equivalent in terms of current , voltage etc. The one you show is surface mount - do you really want that? I googled the diode of the data sheet and there are lot of hits for suppliers , so buy elsewhere?
I live in Lincoln. Good luck with your search for the diode. I fear your problems won't be over when you locate a suitable diode, because the PCB layout of a switching power supply is quite critical.
If you've never designed a switched mode power supply before, then you might be better off buying a ready built module.
Here is a quote from an application note on layout guidelines: Quote. Loads of cheap LM based buck-converters all over eBay. They use the adjustable output voltage version with a turn pot to set the output voltage. Some have an LED voltmeter built in even.
As mentioned above, layout is crucial for a switch-mode power supply, careful control of loop area in the high current paths is needed, although usually datasheets have a suggested layout section you can just copy. Choice of inductor is also crucial, use an inadequate part and the whole circuit can fail, or the inductor overheat.
