Hi, dear, do you want to know what size bridge you need to use when replacing? Here I want to share with you my experience.

I get variations of this question quite often, such as: I don't see the bridge used in the Atari AC power "brick"....

My Tempest manual says I need a MDA3501 bridge & I can't find one....What's a suitable replacement for my T3501... and so on.

Like diodes & many other components, the key is usually in the part number. I have added more info on the Parts Page beside each one listed to better aid you.

But I will put a brief note here, as well. In both the examples cited above the bridge is ...from the part number.... a 35[amp]01[ 100 volt].

Generally speaking the first digit/s will refer to the amperage that the bridge is capable of handling & the ending digit/s the voltage it is capable of handling.

As Scotie would say...if you put a 2501 in place of the cited bridge, she's gonna blow!... since the bridge is only able to handle up to 25 amps of current even though the 100 volts is sufficient.

You could go to an "02" 200 volt, "04" 400 volt or higher & still end up with a blown bridge. You need to at least meet both amperage & voltage of the original when replacing.

A good replacement for the cited bridge would be a 3502... disregarding mrf's prefix or suffix.... for 35 amps & capable of handling 200 volts before popping a leg.

Much like sister components.... diodes, capacitors & resistors, you can safely go beyond specs, but not below.

1N4001 [1A50v] can be replaced by any in the series up to 1N4007 [1A1000V]
100uF 160V cap can be replaced by a 100uF 200V or better cap
220 ohm 1/4w resistor can be replaced by a 220 ohm 1/2w resistor
