SCR Operation & Testing

This video explains how an SCR (Silicon-Controlled-Rectifier) works, and how to test them.

thank you so much. i was so confused in class. and this simple video just cleared everything up for basic electronics course. greetings from Peru.

[CovertCulvert]

Thank you, thank you, thank you! I finally found a video that I could follow to do the test I needed to do.

[AShearer]

Great video and explanation. Thanks for taking the time to put it together.

Believe it or not, the bulb method is the way ive allways tested them, it never fails :-)
Ive also used bigger bulbs to test the stability of larger current scr's when they heat up.
Smashing video :-D

[bobbailey]

Nice! You explain and demonstrate things so clearly :-)

[shamanking]

what size resistor are you using ???
does have to be a 9 volts battery ???
Thanks

Why does the SCR have a larger voltage drop at Vac (anode-cathode) if it uses an AC voltage supply, rather than a DC voltage supply?

Please reply thanks, I already subscribe your channel 👌

Electronic control of tankless water heater: Use a PID? SSR vs SCR?
I have an 8KW Atmor tankless water heater that has two switched heating elements. I want to add stable electronic temperature control. But I can't find good information about the different options!
Seems the PID + SSR MAY have longer switching time, and that MAY reduce heating element life from thermal cycling vs a higher speed SCR. But I am having trouble finding the real answer.

if u want a super sensitive gate use the SCR2p4m it's gate is ultra sensitive i triggerd it using 0.13 volts

Nice video! But what are the factors you need to consider when selecting an SCR for a particular circuit? Which SCR should you use?

[nkkri]

can you short the gate to the anode and use it as a diode? What is the current flowing through the gate? Is that why your using a resistor and what value did you use.

I learned something today! What kind of devices have these in them? I'd like to keep a lookout while salvaging components. Thanks for the video!

Are these only to be tested removed off board out of circuit?
Just documenting how to troubleshoot old pinball machines and 60 of these (mcr106-1 and 2n5060) are on one board alone. I notice 2 already were replaced by seeing different part manufacturers were soldered on.
If I can check on board and won't mess anything up, do I need to do anything afterwards to close gate, if I understand that right..

Nice video men, can we also applied this method of testing for the high power thyristor such the hockey PUK type (ceramic)?

[nathanrice]

My problem is I can't find an SCR for the 12VDC application that I need it for. I need an SCR that can take a 12-15V gate trigger. The highest I can find is a 10V gate trigger SCR. I want to get by without using a resistor.

[CSSIandAssociate]

Thanks for posting. Another great vid.

[kiranshashiny]

Nice video, Why did you have to use the resistor when connecting to the gate ?

[lowprofileneovvl]

Is this method is the same also when testing a big thyristor (ceramic type) used in soft starter? thanks

[ElectronicsShow]

thank you, please i need help regarding a BRY51 i found nothing about it, can i replace it by cr02am thanks

[anujpundir]

Sir plz make a video on IGBT testing and its working.
