How to Select a Diode?? | TVS diode Selection | What is TVS Diode?

[@優さん-n7m]

I thought you were going to spend time comaring Zener with TVS and then also show some lab experiments with results on the scope.

[@guntherswinke3637]

Thanks for the Video. But what happens if the TVS blows up by over current? Does it get high or low impedance? The other question is, if you know the TVS named GFP 78A and a substitution typ for it? Thx!

Thanks for the video. I was just looking at DC to DC converters and it recommended a TVS on the input. Never used one before. I usually use gas discharge tubes for protection.

[@vinaymathapati6800]

Bro I have a project...please help me. I need a diode which can pass a certain voltage,say 5v. It must not conduct if the supplied voltage is lesser or greater than 5v. Please help me.Which diode to use?

[@Ghost572]

Could you not just use a voltage regulator? that way it stays at 5V. It also may be possible to do something with an op-amp comparator, more than likely two op-amp comparators.

[@rajusaha6686]

Excellent Discussion. Thanks a Lot. If you can provide more videos like this, it would be very helpful for people like us.

[@FoolishEngineer]

Yes, Working on it. Thank you so much for watching!!

[@dalenassar9152]

Can TVS diodes be used in series to increase the clamping voltage? THANKS MUCH FOR THE GREAT VIDEO!!!

[@engjds]

Good video, but its good to have an indication of what voltages are too high for a TVS, seems TVS are made upto 1Kv these days, so why would you choose MOV's?

[@electronicrepairservice1705]

Great explanation. Would like to know more ... how to add to an existing board ie power supply, best place to use on a circuit board ie power supply board, how to locate a TVS diode on a board.

Nice video man! Well structured

[@muralipenta9568]

Hi , Can you provide little more detailed/depth on TVS diode. Means how to validate the TVS diode power dissipation, current handling capacity while applying any surges as stated in the IEC 61000-4-x standards

[@rusty_junk]

Hi what is best for gigabit ethernet where my port has built in magnetics and the TVS would be between the port and PHY? Unidirectional or bidirectional? Also if the PHY has a max input voltage of 5V will a clamping voltage that is higher than 5V stress the PHY and cause damage? If so, then I am lost because I can't seem to find a TVS with a clamping voltage below 5V. Any help is appreciated. Thanks.

[@FoolishEngineer]

You will have to check how much transient comes from the Ethernet port? you will get it in the datasheet or you can ask the supplier about its data. Same for the PHY. If PHY is not able to handle the supply over 5V then my friend you will not find TVS with that configuration, I would suggest you to use a Zener diode of Vz 5.2V. If the transient comes Zener diode will act slowly but still you will have a protection at the input, although it is not the best practice to use a zener but if your are out of options then this can help.

[@davidwilliams-xw1iy]

how do you determine if a transient Voltage Surge Suppressor (TVSS) is good or bad using an ohmmeter?

[@engjds]

Use a resistance check, it most often fails short, like less than 10R, but they can fail open too, that is only possible to check building a test circuit with a voltage supply capable of reaching its breakdown voltage. My advice, check for a short, check visually for puncture marks through the package, if both look ok, assume its working.

[@pratahsinnetamby]

Thanks for the great video. In the comparison between MOVs and TVS you mentioned high and low voltages. What is the range of voltage that you would consider to be high. I'm sure the specs would give me a hint. The reason I ask is that I am attempting to build a irrigation controller and the valves run on 24VAC and each time they switch on or off there is a spike. The commercial controller that I had seemed to be using MOVs in the circuit. Your video on MOVs gave me a better idea on how to size them. Many thanks again.

[@smichaelnicholas]

do you have any circuit that works under 220 V with TVS diode??

[@FoolishEngineer]

I am sorry, I don't.

[@gabrielquarshie94]

Very good explanation of these Components

[@FoolishEngineer]

Thank you!!!

Excellent overview. I discovered the existence of TVS diodes the other day and I bought some via Digikey. I was using a regular IN4004 diode as a commutating diode across a 24Vdc inductive load but it’s too slow and my manual toggle switch still arced. I hope the SA30A TVS diode I bought will do the trick.

[@FoolishEngineer]

Did it work?

How to select & when to select tvs diode according to design calculation

[@triplemtechnology3600]

Kindly add unidirectional and bi-directional TVS diode application.

[@multitechservicepoint4917]

How to test tvs diode plz help

[@FoolishEngineer]

You can't test TVS diode like that. We need to provide specific pulses and should have a DSO

[@LTeyler]

Very good examples with technical information. Thank you, -General3

[@bobcongleton9220]

Cover the Sidactors, and Transorbs next... this was a good review and comparison....

Sure!! I'll do it

[@wtfucrazy]

Good video. One question: When to use bidirectional and when to use unidirectional TVS diode? Any examples?

[@Truth_seeker_24]

In some circuits example a 75ohm cable coming from a dish outside your house to the receiver in your house there can be surges and lightning strike to your ground sleeve of coax. That’s were we use bidirectional tvs on the receiver. But basically when you have both positive and negative swinging signals being applied to your Vin then user bi-directional tvs didoes.

Hello, My Project: I need a 2 pin Bidirectional TVS Voltage Clamping Diode (NOT Zener) to protect a Full wave bridge rectifier circuit - battery (switching reserve power inline) charging circuit & Lighting as the Load. Both the charging circuit & Load will be 7.5 volt with current between 500mh & 2amps. The power supply will be from a Shimano bicycle Hub dynamo (actually an Alternator) the voltage can go very high when the wheel is spinning at very high speeds down hill up to 140volts open circuit. So I need to clamp the AC Voltage to 8.5volts before the Full wave bridge Rectifier allowing an extra 1 volt than the circuit needs (7.5V) for forward voltage drop across the Schottky diodes & consumed by the circuit components. So in a nut shell I only want 8.5V AC to enter the Rectifier but all the current & the circuit needs 7.5V at a minimum 500mh but up to 2Amps. I'm confused as to what Bidirectional TVS Diode (NOT Zener diode) I need. Please advice Cheers,

[@mathaithomas3642]

How tvs diode looks like? You have only mov picture !?

[@FoolishEngineer]

I just looks like a normal PN junction diode

Difference between Unidirectional & bidirectional TVS diode

[@FoolishEngineer]

Bidirectional diode works from both sides

[@mertsamet2953]

hello foolish engineer . my city voltage is about 230 v .. i want my protection to absorb small voltage spikes . computer , monitor ,, psu .. etc ((note ; i will use 2 amper fuse before mov or tvs diode )) . what protection is suitable for me ? and its value ?

[@FoolishEngineer]

Use MOV.

[@mertsamet2953]
