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....
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!
