Hello dear visitors to my channel! In this article we continue with you to get acquainted with the rules of verification of various electronic components. And today, our hero will be the IGBT transistor.

A bit of theory

Basis for the work insulated-gate bipolar transistor is taken to use n - channel MOS - low-power transistor for switching high-power bipolar transistor. This product turned out to combine the best of bipolar and field-effect transistors.

Insulated-gate bipolar transistor (IGBT) found broad applications in many modern appliances. For example, most modern welding equipment necessary in its design are an assembly of IGBT transistors.

Graphically, this element is represented as follows.

Pictogram transistor circuits where G - the shutter, C- collector, E - emitter.

Check the IGBT transistor multimeter

Now, let's move from words to deeds and check multimeter transistor STGW45HF60WD.

First we need to find out where the element has an emitter, a collector and a gate. To do this, open any search engine and look for the Datasheet in our element.

Once we know the purpose of each pin, you can proceed to the check of operation. To do this, take a meter and put on a dial control and measure the brightness between the gate and the emitter.

Thus, we will check our transistor to a possible "short stack". If the meter shows "1", it means everything is OK and you can continue measurement, and if the instrument will show "zero", the product is defective.

Now probes to measure the brightness between the gate and collector, as well checking for a possible short circuit.

Next, using a jumper or any metal object bridged output transistor for a few seconds. In this way we are guaranteed close it.

After this re-take the multimeter and the "minus" (the black lead) is connected to the collector, and the "plus" (red probe) to the emitter. In this case, the display multimeter, you will see the voltage drop across the internal diode.

Now we change places and probes multimeter should show "1". This means that there is no leakage in the transistor and the internal circuit.

In addition, you can build a simple circuit with the help of which you just guaranteed check transistor performance even without test equipment.

So if the button is squeezed, the bulb will be lit and the rest position no.

That's the simple way you can test the functionality of the IGBT (IGBT) transistor. If you liked the material, and you want to see in their stream longer like, then put Like and subscribe. And in the comments, you can write on any topic you want to read the article.
