Post by thread:[EE]: BYV26-200 information sought. ''

Anyone know anything about a BYV26-200 diode.? The BYV26-x series (x = A ... G) is an ultra fast 1 amp rectifer in voltages ranging from 200 to 1000v Pkg is SOD57 (glass ball) with 0.8mm leads I have some more ancient BYV26-200 diodes for which I can find no data (not even on Philips website along with the BYV26-x ) The BYV26-200 is in a SOD-64 pkg (slightly larger glass ball with 1.35mm leads - very fat and nasty to bend etc). Findchips knows them not an a general web search gives no strikes. I would not be overly bothered by old tech diodes EXCEPT that they seem to be rather more robust in a particular application than their modern kin and I was wondering why. I would not have expect them to have a higher current rating but the brutally rugged SOD-64 pkg suggests they may have.

Comrade Russell; I am looking at the General Semiconductor databook, which kind of agrees with your numbers. They have BYV26D and E, with 800 and 1000V resp. They come in a DO-204AP package (thru hole). Chris~ Russell McMahon wrote: {Quote hidden}> Anyone know anything about a BYV26-200 diode.? > > The BYV26-x series (x = A ...

It is probably an avalanche protected diode. I remember there was a lot of hype when these were introduced, and I remember them as being packaged like that. The avalanche protection operates at about the turn off point as it goes into reverse conduction, and causes the diode to turn off sooner, and with a more rounded waveshape if I recall correctly. -- http://www.piclist.com hint: To leave the PICList .....piclist-unsubscribe-requestKILLspam.....mitvma.mit.edu
