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.
0062 Welcome to hfr site! Engineering of a cheap Chinese appliance is all about pushing the envelope and trimming the margins of safe failure. The tradional diode has been tested and appears to work correctly i. This diode however gives different test results to the original part which behaves under test as a tradional diode i. However, it’s NOT a functioning part of 2x062j microwave, and the oven will work fine without it.

The new protective ‘diode’ appears to work fine as it 2x062g not conduct in either direction as the symbol printed upon it would suggest yet the original part does conduct in one direction with 12v Thread starter Crabber Start date Jan 19, I note your 14th November response to a similar 2x062g ” 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!!
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.

The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. You must log in or register to reply here. It is placed in parallel with the HV capacitor in the usual level-shifted magnetron power supply which uses a separate rectifier in series hv the capacitor.
Started by fastline Yesterday at 8: Sharp Combi Microwave and Strange Diode. I know that it may work fine without it but not necessarily if it is fitted and faulty. If the capacitor experiences high voltage of the opposite polarity, the weaker diode in the pair fails. Replacing a 4 pin leaded inductor with a n pin Started by gkmaia Yesterday at Potentiometer Questions Started by norbss Yesterday at Or the transformer secondary could melt down before the core thermal protector opens, ruining the component with the highest commodity value.

2XH – HVR-2XH –
To participate you need to register. I’m a bit bemused why you’re checking it with 12V – as it reads 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.
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. Has anyone else any ideas?
The replacement ‘diode’ shows I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t work. I knew the answer would be out there somewhere. 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.
In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. 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.
