Temperature dependence of a silicon diodes reverse current?

Jan 09, 2007 2 Replies

I have two text books that say the reverse saturation current for silicon semiconductor diodes will approximately double in magnitude for every 10 degree C rise in temperature. Two other textbooks I have say the reverse saturation current for silicon semiconductor diodes will approximately double in magnitude for every 5 degree C rise in temperatue. None of the 4 books provide an explanation of why the reverse saturation current doubles for evrery 5 or 10 degree rise in temperature. There for my question is why do some authors say the reverse saturation current approximately doubles for every 5 degree C rise in temperature and other authors say it approximately doubles for every 10 degree C rise in temperature?

The keyword is "approximately".

Naaah! It *triples* for every 10°C ;-)
