This kind of component is effectively two diodes in series, one with a high reverse breakdown voltage rating and hbr other with a much lower rating.
From a posting by Carl Willis who has posted the below on fusor. Its purpose in that configuration is to allow the hgr 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. Just saying hello Started by MichaelaJoy Yesterday at 6: Sharp Combi Microwave and Strange Diode. In any case, I suspect the “protection diode” is only designed to carry current in the permanently-failed state, making nvr not worth much to you.

Media New media New comments Search media. The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. 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.
I’m a bit bemused why you’re checking it with 12V – as it reads However, it’s 2x062g a functioning part of a microwave, and the oven will work fine without it. Click here to register now.
2XH – HVR-2XH –
Perhaps I didn’t make myself clear enough. Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.
Thread starter Crabber Start date Jan 19, Has anyone else any ideas? 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 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!!
Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails.
To participate you need to register. Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value.
I knew the answer would be out there somewhere. Hi, I have a combination type Sharp microwave however the microwave function has failed.

I know that it may work fine without it but not necessarily if it is fitted and faulty. You must log in or register to reply here. The HV rectifier does not appear to have failed as it has 7. Crabber New Member Jan 19, Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at 2s062h 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.
This diode however 06 different test results to the original part which behaves under test as a tradional diode i.
