How to check MOSFET with multimeter (हिन्दी)

2071 ratings | 290711 views
www.arieslaptop.in [email protected] MOSFET is a field-effect transistor in which there is a thin layer of silicon oxide between the gate and the channel. MOSFET used in Desktop and Laptop motherboards there are two different types of MOSFET N-Channel MOSFET. P-Channel MOSFET. N-Channel MOSFET Used in Desktop motherboards while in Laptops (motherboard) both N-Channel and P-Channel MOSFET are used. Ok! Enough talk about introducing MOSFET lets Do the testing Process and see which MOSFET is working one and which one is non-working. During testing I will show you which one is P-Channel and which one is N-Channel MOSFET. To test a MOSFET we will need a Multimeter and some working and non-working MOSFET. Mulitimeter-with-MOSFET Ok as we can see MOSFET consist of 3(three) pins 1) Gate 2) Drain 3) Source Gate-Drain-Source-MOSFET Now set your Multimeter to (Continuity Beeper) and Black Probe to Common Ground and Red Probe to Ohms(Everything but Ammeter). Touch Both Red Probe and Black Probe and if your hear a beep sound than you are ready for testing MOSFET. First we will check if this MOSFET is N-Channel or P-Channel. N-Channel MOSFET: Connect Black Probe to the Drain and Red Probe to the Source of MOSFET and if you get any Value on screen of Multimeter than this MOSFET is N-Channel MOSFET.If you did not get any value than better try second one. P-Channel MOSFET: Connect Red Probe to Drain and Black Probe to Source and if you get any Value than its P-Channel MOSFET. So now we know how to find P-Channel and N-Channel MOSFET so its time to test if its in working condition or not. N-channel Working MOSFET: Now Pick a N-channel MOSFET and connect Black Probe to Drain and Red Probe to Gate if you don’t see any value than its working MOSFET.If you see some Value than its a (short MOSFET, a leaked MOSFET or not a MOSFET at all). As its working MOSFET lets charge this MOSFET, connect Black Probe to Drain and touch Red Probe for few seconds to Gate and than Touch Red Probe To Source while Black Probe should stay Connected to Drain and you will here a beep which shows that your MOSFET is charged and in working condition.Remember to do the same test again you have to release to charge from MOSFET you can do this by Holding a MOSFET for few seconds between you fingers or just connect Black Probe to all three Pins at same time. P-Channel Working MOSFET: If you have a P-Channel MOSFET than connect Red Probe to Drain and Black Probe to Gate and if you don’t see any value than its a working P-Channel MOSFET but if you see some value than probably this MOSFET is Short or leaked MOSFET. To charge a working P-Channel MOSFET connect Red Probe to the Drain and touch Black Probe to Gate for few seconds and bring back the Black Probe to Source and you will hear a beep sound which means your P-Channel MOSFET is charged and good to go.

Sir, can we substitute AO4712. (laptop mosfet ) with SM3113N (Desktop motherboard mosfet) as datasheet parameters match but sm3113n with 85amp, as of ao4712 ,13amp Reply awaiting sir, thanks in advance.
Harshad Patel (5 months ago)
Replace 4712 instead of sm3113n , but you can't replace sm3113 to 4712

Sir good morning Jis tarah aapne mosfet ki picture draw krke dikhai hai ki mosfet ke ander 1doide hota hai agar doide ka cothore drain se connect hai to vo n channel mosfet hai mera aap se 1 prashn hai desktop mein n channel mosfet prayog ki jate hai jb ham drain pr yani cothore pr positive supply dege do hame source pr positive supply kaise milegi kyoki hamne drain pr positive supply di hai aapko pta hai koi bhi doide forword bios mein kam krta hai .......... Agar hamne n channel prayog kiya aur uske drain pr positive supply di to vo to reverse bios ho gya vo kam kaise krta hai
pardeep kumar (8 months ago)
Harshad Patel ok
Harshad Patel (8 months ago)
यहाँ पे mosfet by default switch off रहेगा और वह तभी सप्लाई पास करेगा जब gate उसको बोलेगा एक और बात , अगर सप्लाई को always पास करना हीं है तो फिर mosfet क्यों लगाए ? Diode हीं ना लगा दे ?? लेकिन mosfet लगा है मतलब ओफ़ के लिए लगा है
Harshad Patel (8 months ago)
Diode से हमें सप्लाई पास नहीं करनी है इसी लिए तो ऐसे लगाते है ... यह पे drain से पॉज़िटिव सप्लाई देना यानी की रोक देना है सप्लाई को source की और जाने के लिए ।। लेकिन जब हम गेट से trigger करते है तब सप्लाई drain to source । gate के कारण होगा

sunny baba (11 months ago)
Sir is it necessary to hear a beep from a mofset to determine it bad? Or if we get a value from gate no matter n channel or p channel also determines bad mofset? M waiting for ur reply
sunny baba (11 months ago)
Harshad Patel thank you sir for ur quick reply. I want to know that what if a mosfet gives u value of 13 in source with beep and 1 in gate is that bad mosfet? And 2 mosfet giving me the value of 109 in source but no beep that is also low as u said source must be 400 to 600 and gate with 1 is that also bad or not?
Harshad Patel (11 months ago)
+sunny baba gate never show value with drain and source ... Its thumb rule
Harshad Patel (11 months ago)
+sunny baba no .. some mosfer switching fast so may be beep it and goes to main value. If multimeter battery is low then also happen it same

how will we difference it is MOSFET or NPN transistor?and how will we identify the MOSFET on electronic board?
