carl0s Posted December 7, 2004 Share Posted December 7, 2004 Hi chaps. I need 2x 5.1V Zener diodes, now. How can I identify a diode as being a Zener diode, and being 5.1v? I want to pull a couple off something.. I have all sorts of electronics stuff I can pull apart. I bought a load of stuff from RS today, including some 1N4148 signal barrier diodes, but I need these two Zener diodes. HEEEELP! pretty please Quote Link to comment Share on other sites More sharing options...
carl0s Posted December 7, 2004 Author Share Posted December 7, 2004 p.s I know what a diode looks like, I just don't know how to identify them Quote Link to comment Share on other sites More sharing options...
merckx Posted December 7, 2004 Share Posted December 7, 2004 They are usually identified by the code on the body as being BZYC5V1 the 5V1 being 5.1V:) Quote Link to comment Share on other sites More sharing options...
carl0s Posted December 7, 2004 Author Share Posted December 7, 2004 hoky dokey, that's a start.. have to use this awesome camera as my magnifying glass though eh. so the 5V1 is fine.. how do I know it's a Zener diode? Are they the non-glass ones? or wot? Quote Link to comment Share on other sites More sharing options...
Digsy Posted December 7, 2004 Share Posted December 7, 2004 You can get normal diodes in glass packages and "black" packages. Zener diodes have very different characteristics to normal diodes. If in doubt, buy new ones. They probably only cost a few pence. Quote Link to comment Share on other sites More sharing options...

carl0s Posted December 8, 2004 Author Share Posted December 8, 2004 Right, I'll be off back to RS shortly. Do I just ask for a couple of 5.1V Zener diodes? Obviously that's quite a generic request, will they all do the same job, within reason? This looks like the puppy, from http://www.rswww.com: Description Diode, Zener, axial, BZX79, 5.1V RS Stock No. 446-8674 Manufacturer PHILIPS SEMICONDUCTORS Part No. BZX79C5V1A26A Quote Link to comment Share on other sites More sharing options...
