MOSFET transistor is the most used transistor when it comes to power electronics or where we need high impedance.
To check if the MOSFET we have is good or bad we need to have the best MOSFET tester in our lab.
Sure we can test it by using a multimeter. But using a multimeter is tedious and not that straightforward.
At the end of this article, you should be able to know:
- A list of best MOSFET transistors recommended and used by field professionals
- How to use a MOSFET tester
Sounds interesting? Then, let’s get started.
Best MOSFET tester
MOSFET stands for metal oxide semiconductor field effect transistor. It has three terminals:
- Gate (G)
- Drain (D)
- Source (S)
The main use of these transistors is in power electronics.
Because of high power handling, they often become damaged. And require replacement.
To check the bad ones we need to have the quality best MOSFET testers in our lab.
The best MOSFET tester that I and other field professional recommend is either the m328 tester, the DCA pro, or the Bside ESR02 Pro.
They are the best because thousands of people have used them and got the results they want. They are reliable. And comes with a decent price tag.
Before getting into the main list of the tester. Let’s first see what you should look for selecting your tester.
Choosing the best MOSFET tester
Following are the key things that one should not miss:
- Clear display – like the tester must have a clear display with clear readings
- Easy operation
- Overcurrent and overvoltage protection
- Solid component holding socket
- Accuracy
- Auto turn off feature – to save battery consumption
Alright!
Let’s move toward our amazing tester list.
List of MOSFET testers
Let’s have a look at some MOSFET testers. A MOSFET tester can save you a lot of time if you are the guy working all day long with power electronic circuits.
1. Peak Atlas DCA75
Starting our list with DCA75 from the Peak brand.
Peak is a famous brand for making various types of component testing tools.
The tester, DCA75 from this brand, is an advanced level MOSFET tester. It has a curve tracer as well.
Like if you want to draw the “Ic Vs Vce” curve (for transistors) then this device can do it for you in a matter of seconds.
The best part of this tester is no matter how you connect the MOSFET transistor. It will give you its right in configuration.
Here is the link Atlas DCA Pro (Amazon link) for your own further investigation.
2. M328 Component tester
Moving to our next best MOSFET tester, the M328 component tester. It is awesome and has a nice color display. You can use it for a wide range of applications.
The main selling point of this tester is to save you the tedious MOSFET testing work. Where you use a multimeter and write down various values and then compare them with the datasheet.
With this tester, just plug in the MOSFET and get the results (see if it is bad or good) – it is that simple.
Key Features of m328 tester:
We can identify and test the following components with the device with high accuracy:
- Transistors (All types including BJT, MOSFETS, FETs), the M328 will automatically identify the transistor type, the right pin configurations, DC beta, and much more.
- Diodes (including PIN, Schottky, and Zenor).
- MOS
- SCR
- Resistors including variable resistors i.e., potentiometers.
- Capacitors, this little guy is capable of actually measuring the capacitor ESR value with much accuracy.
- Inductors
In summary, the m328 transistor tester (Amazon link) is the best MOSFET and component tester that you can have in your lab for electronics projects. It will make your testing very easy.
3. BSIDE ESR02 PRO
The next tester is the ESR02 Pro from the BSIDE brand.
This MOSFET tester has an option for SMD components as well. It will be you all in one component tester.
Important features:
- It can also be used to test different kinds of triodes
- Thyristors (SCR)
- MOSFET
- The polarity of the pin
- Output Hfe
- The junction capacitance of the FET
In a short summary, the BSIDE ESR02 Pro (Amazon link) can be your all in one component tester. You can use it to find out N-channel and P-channel MOSFET. Also, you can use it to find it if the MOSFET is good r bad.
4. Oscilloscope MOSFET tester
This one is different from the above all. It is an oscilloscope and a MOSFET tester combined. With this you get more accurate results.
Important features:
- Real-time sampling rate of up to 2.5MS/s and 200MHz analog bandwidth
- USB Type-C charging port
- MOSFET testing feature
- High definition LCD screen
In a short summary, the Oscilloscope MOSFET tester (Amazon link) ingeniously integrates digital oscilloscope, electronic component tester, PWM signal generator and other functions into one.
Bring more practical functions to you with a small size.
5. TC1 MOSFET Tester
Next best MOSFET check meter is the TC1 component tester. It is portable and comes with rechargeable batteries.
It has socket as well as plugs for connecting the components and MOSFET.
Important features of this meter:
- Color display with clear readings
- Automatically identify and MOSFET, IGBT, and JFET.
- Besides transistors, it can also test these components Triac, resistor, diode, triode capacitor, and other components.
- One key operation, connect the component, press the test button, and get the results.
- Auto Power Off, to save battery power when not in use for a while.
- Extra plugs to test components more easily and simply.
In summary, the TC1 component tester (Amazon Link) is very easy to use and can be a good testing tool for your lab and projects.
6. MK-328 MOSFET Tester
This is our last transistor tester to explore. This belongs to the above MK -168 family, but it is a much more advanced model.
Important features:
- Measure the gate threshold voltage and gate capacity for MOSFET
- All symbols are surrounded by the probe number of the Tester
- Up to two diodes are displayed in the correct order and diode symbol
- Key operation for automatic shutdown
You can see it has a bigger screen than the above. To know further about this guy, here is the link for your further investigation, MK-328 Transistor Tester (Amazon link).
It is a great time saver because one button press tests most common components just by plugging into it without thinking about polarity or voltage.
7. MK-168 Tester
This component tester is far more sophisticated than the rest of the above. Instead of just a socket or plug, this tester has an option for both.
You just plug your MOSFET. Press the test button. And get the results on the screen.
If this guy got your attention. Then, here is the link MK-168 (Amazon link) to gather more info about this amazing transistor tester.
Conclusion
When working with power electronics, testing out different components especially MOSFET and measuring their values and other parameters is a time-consuming task.
You have one option, that is to use a digital multimeter.
But to test a MOSFET with a multimeter. First, we need to take the exact measuring steps. Then we need to verify those values and some time to remember some values.
To avoid the above tedious task, there is an alternative. The alternative is to use the best MOSFET tester.
A MOSFET transistor tester is a tool that tell you right away if you have a good or a bad MOSFET. Thus saving you a lot of time and lab resources.
So guys, that is it. That I want to share about the best MOSFET testers. I hope I was helpful.
Thank you and have a grateful life.
