Hello everyone.
I have a device that is used to shape the human body muscels and burns fat. Works on the principle of electromagnetic impulses. One thyristor in side is shorted which has only this unknown mark on it ( QC230301 ). I can't find any information about it anywhere on the Internet. I tried to replace that thyristor with one of 1.6kv 800A and after 5min. of work he has burned out again, which means that he is probably weak. There is no schematic diagram on the internet, but that didn't suprise me because all the transistors and chips that are on the boards have their markings...
Hello Everyone,
I have 1 diode on a circuit that I suspected to be faulty because the forward and reverse bias has a voltage drop reading.
While compared to the reading of another diode from the next channel it won't read at reverse bias.
Now the problem is; it does not have any body marking.
So I tried to sketch the diagram and found out that it is connected to the base and collector of the C3632 transistor.
What do you think is this diode?
Can you please suggest what part number can i use to replace this faulty diode instead?
