Crabber New Member Jan 19, 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. 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 Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

Hi, I have a combination type Sharp microwave however the microwave function has failed. Forums Uvr posts Search forums. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it.


The replacement ‘diode’ shows I’m new to electronics but have read elsewhere on this forum about a popular fault with Sharp microwaves being a strange protective j 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.

This diode however gives different test results to the original part which behaves under test as a tradional diode i. The HV rectifier does not appear to have 2x06h2 as it has 7.

Has anyone else any ideas? This kind of component is effectively two diodes in series, one with a high reverse breakdown voltage rating and the other with a much lower rating. Sharp Combi Microwave and Strange Diode. Welcome tosite!

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. I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t hcr. Hi Nigel and thank you for your reply. From a posting by Carl Willis who has posted the below on fusor.


In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. Just saying hello Started by MichaelaJoy Yesterday at 6: Its purpose in that 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.

I think I have found the answer to my question and one that has been raised on this forum previously. 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.


The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. Perhaps I didn’t make myself clear enough.

Potentiometer Questions Started by norbss Yesterday at Started by fastline Yesterday at 8: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday mm 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 n components to not “go gentle into that good night. 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 2x06h2 clear of microwaves!!

Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the uvr commodity value. I knew the answer would be out there somewhere. The tradional diode has been tested and appears to work correctly i. You must log in or register to reply here.
