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

Just saying hello Started by MichaelaJoy Yesterday at 6: I have purchased and fitted a replacement 2XH diode but the microwave still doesn’t work. Potentiometer Questions Started by norbss Yesterday at 2062h here to register now.
Hi Nigel and thank you for your reply. Crabber New Member Jan 19, Welcome to our site! I don’t know precisely what condition is being protected against, but my guess is that a high 2x06h 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.
The strange ‘diode’ is marked as if it is actually comprised of 2 diodes connected together negative to negative and is labelled 2XH. Replacing a 4 pin 2x602h inductor with a 2 pin Started by 2x062j Yesterday at Perhaps I didn’t make myself clear enough. Sharp Combi Microwave and Strange Diode. Thread starter Crabber Start date Jan 19, Hi, I have a combination type Sharp microwave however the microwave function has failed.
The tradional diode has been tested and appears to work correctly i. Started by fastline Yesterday at 8: 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!! Forums New posts Search forums. 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 2c062h second tradionally labelled diode HVR-1X7 which is connected positive side to one side of the capacitor with the negative side to earth.
You must log in or register to reply here. In my case this bidirectional diode failed in one direction as it is supposed to together with a secondary fuse. 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.
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.

Has anyone 2062h any ideas? I think I have found the answer to my question and one that has been raised on this forum previously. Articles Top Articles Search resources.
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.
From a posting by Carl Willis who has posted the below on fusor. The replacement ‘diode’ shows In any case, I suspect the “protection diode” is only designed to carry 2xx062h in the permanently-failed state, making it not worth much to you.

It is placed in parallel with the HV capacitor in the usual mm magnetron power supply which uses a separate rectifier in series with the capacitor. However, it’s NOT a functioning part of a microwave, and the oven will work fine without it. How do these diodes work and any suggestions as to the problem with my microwave?
