Testing SCR – How To Test And Check Silicon Controlled Rectifier

Testing SCR (silicon controlled rectifier) should be possible by utilizing a simple multi meter or practice analyzer, (for example, the Peak electronic map SCR888

  book segment analyzer) intended to check semiconductor gadgets without any problem. SCR can be found in numerous electronic circuits. Part numbers, for example, the FOR3G and MCR 100-6 were exceptionally normal utilized in PC screen. Some called SCR as thyristor yet in established truth the word thyristor ought not be related only with the silicon controlled rectifier. It is in reality a general name given to every one of the four layer PNPN gadgets including the regularly utilized SCR. The diac, the Triac, and the SCS are the other well known gadgets having a place with the group of thyristors.

SCR comprises of three pin of Gate (G), Anode (An) and Cathode (C). So as to distinguish the pin out, one must discover it from semiconductor information book such the renowned Philips ECG ace semiconductor substitution manage. The information book will rattle off the general determination of the SCR, for example, the volt and ampere. On the off chance that you need to know more insights concerning a specific SCR, you can generally attempt to look from the web. Generally the SCR producers will give the full datasheet to the individuals who need it.

When you realize the pin outs of the G, An and C legs you can start to test the SCR. In the event that you have the Peak electronic map book segment analyzer, what you have to do is to associate the three little clasps to each stick of the SCR (any part number will do). The analyzer will start to examine the SCR and brief you with the showcase, for example, “Delicate or low force thyristor” before it reveals to you the specific pin outs of G, An and C. After the primary test, the analyzer will in the end show you the appropriate response at the LCD show. Red is Gate, Green is Cathode and Blue is Anode. It is a basic procedure and you will know the appropriate response in under 10 seconds. On the off chance that there is an issue in the SCR, the analyzer would not have the option to show the outcomes rather it shows a shorted perusing.

In the event that you don’t have this analyzer for checking SCR, I’m demonstrating you another simple route on the most proficient method to test SCR quick. You need a simple meter set to X1 ohm. Spot the red test to the Cathode and dark test to the Anode pin. As of now the meter doesn’t show any perusing. Presently tenderly move the dark test and contact the Gate pin (the dark test despite everything contacting the Anode pin) and you will see the meter’s pointer will kick as appeared at the image (low opposition).
