Welcome to our site! Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. This diode however gives different test results to the original part which behaves under test as a tradional diode 0622. The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH.

Hi Nigel and thank you for your reply. Just saying hello Started by MichaelaJoy Yesterday at 6: I have purchased 602 fitted a replacement 2XH diode but the microwave still doesn’t work. Hi, I have a combination type Sharp microwave however the microwave function has failed.

Its purpose in bvr configuration is to allow the capacitor to charge to a high voltage of the correct polarity only negative at the magnetron cathodewhich is blocked by the high-breakdown diode in the back-to-back arrangement. Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value.

The HV rectifier does not appear to have failed as it has 7. I think I have found the answer to my question and one that has been raised on this forum previously. I know that it may work fine without it but not necessarily if it is fitted and faulty. How do these diodes work and any suggestions as to the problem with my microwave? If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails.


Sharp Combi Microwave and Strange Diode. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it. The tradional diode has been tested and appears to work correctly i.

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.

I’m new to electronics but have read elsewhere on this forum about a popular fault with Sharp microwaves being a strange protective ‘diode’ that is positioned across the terminals of the large capacitor together with a second tradionally labelled diode HVR-1X7 which is connected positive side to one side of the capacitor with the negative side to earth. Perhaps I didn’t make myself clear enough. I note your 14th November response to a similar query ” It’s a special diode, created this this specific purpose – no idea how it works, and care even less ” I’ll assume that you still don’t know and perhaps we should both steer clear of microwaves!!

Crabber New Member Jan 19, In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. The replacement ‘diode’ shows 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 Potentiometer Questions Started by norbss Yesterday at From a posting by Carl Willis who has posted the below on fusor.

Started by fastline Yesterday at 8: 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. Articles Top Articles Search resources.

I’m a bit bemused why you’re checking it with 12V – as it reads In any case, I suspect the “protection diode” is only designed to carry current in the permanently-failed state, making it not worth much to you.
