MK - N3EAQ ____________________________________________________________________________ _______________________________________ Hi Folks, I'm working on the audio 1st stage of a Gates BC-1H transmitter. It has a rectifier with 4 zener diodes however, unlike most set ups where there are 4 of the same diode, this is using 3 different types, all of the same class, but with just a wee bit different specs.... It's using: 2x 1N3337A - 75V Zener (540 mA max, 56 Vrev Max) 1x 1N3338A - 82V Zener (490 mA max, 62.2 Vrev Max) 1x 1N3340A - 100v Zener (400 mA max, 76 Vrev Max) I only note above where the values are significantly different.... I'm just curious... Why do it with these 3 different diodes??? What does that buy them? Would the world end if I used 4 of the 1N3340A - 100V Zeners (since I have a slug of them in my parts box) as replacements?? Your sage wisdom is appreciated!
