mustang guy Posted January 17, 2018 Share Posted January 17, 2018 I think the R reverses the cathode and anode as stud as compared the the regular 3996 or the 3996A. 1N3996 and 1N3996A has this: http://www.digitroncorp.com/Documents/Dimensions/Zener-DO-4.aspx?ext=.pdf 1N3996R and 1N3996RA has this: http://www.digitroncorp.com/Documents/Dimensions/Zener-DO-4R.aspx?ext=.pdf Quote Link to comment Share on other sites More sharing options...

babadono Posted January 17, 2018 Share Posted January 17, 2018 BTW the zeners did not prevent me from blowing a T35 (K77)tweeter or two in the last 40 years Get a better tweeter...just sayin Quote Link to comment Share on other sites More sharing options...

Not sure. I thought diodes had a flow path. A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance Quote Link to comment Share on other sites More sharing options...
babadono Posted January 17, 2018 Share Posted January 17, 2018 Zeners are special critters. In one direction(polarity) they stop conduction until their "zener" voltage is exceeded. Then they "avalanche" and conduct which limits the voltage across them to their zener voltage. In the other direction they conduct like a regular forward biased diode.

Those are interesting little diodes. Quote Link to comment Share on other sites More sharing options...
