What IC is this??? [Copy link]

 

How knowledgeable are you? What kind of electronic device is this (the IC circled in the picture below)? It is used in the power supply. Is it an inductor?

I've seen it before, don't know what it was.

I searched on Taobao for several days but couldn't find anything similar. After another circuit board was dug out and filled with glue, the font was blurry and unclear.

It should be a discharge tube, which has a high voltage protection function at the input end.

Lightning protection is also commonly used

The moderator is really knowledgeable. I have been searching for a week but still have no clue.

It is indeed a high voltage, reverse boost circuit, used to light up the lamp. Does this thing have any parameters?

Several parameters are very important, impulse discharge voltage, DC discharge voltage, impulse withstand current

When using it, you need to look at the parameters of the discharge tube and the requirements of your own circuit.

Our forum has introduced Langtuo Electronics, the discharge tube is very useful

You can contact him and ask for some information about discharge tubes.

Great! Let me see

qwqwqw2088 on the second floor said it very accurately. This is a gas discharge tube, which is often used for overvoltage protection.

Gas discharge tubes are not used very often.

It's still in the testing phase, and the rest has not been determined yet.
