It is placed in parallel with the HV capacitor in the usual level-shifted magnetron power supply which uses a separate rectifier in series with the capacitor.

Its purpose in that configuration is to allow the hve to charge to a high voltage of the correct polarity 2x62h negative at the magnetron cathodewhich is blocked by the high-breakdown diode in the back-to-back arrangement.

Potentiometer Questions Started by norbss Hve at Crabber New Member Jan 19, If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails. The new protective ‘diode’ appears to work fine as it will not conduct in either direction as the symbol printed upon it would suggest yet the original part does conduct in one direction with 12v I don’t know precisely what condition is being protected against, but my guess is that a high reactive current circulating through the transformer-capacitor pursuant to a failed main rectifier or gassed-out maggie could cause one or both of these components to not “go gentle into that good night.


This diode however gives different test results to the original part which behaves under test as a tradional diode i.

In any case, I suspect the “protection diode” is only designed to carry current in the permanently-failed state, making it not worth much 2x602h you. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it.

The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH.

Welcome to our site! This kind of component is effectively two diodes in series, one with a high reverse breakdown voltage rating and hv other with a much lower rating. The tradional diode has been tested and appears to work correctly i.

In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse.


Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value.

I think I have found the answer to my question and one that has been raised on this forum previously. The HV rectifier does not appear to have failed as it has 7. How do these diodes work and any suggestions as to the problem with my microwave? Thread starter Crabber Start date Jan 19, I’m a bit bemused why you’re checking it with 12V – as it reads
