The IRF3205 leading-edge N-Channel HEXFET® Power MOSFETs from International Rectifier implements hi-tech processing solutions to attain incredibly minimal on-resistance per silicon space. This advantage, along with the rapid converting rate and ruggedized system layout that HEXFET power MOSFETs are popular for, offers the developer with an exceptionally cost-efficient and dependable product to be used in an array of programs. The TO-220 bundle is globally favored for most of commercial-industrial purposes at power dissipation stages to around 50 watts. The minimal thermal resistance and reduced packet price of the TO-220 play a role to its extensive recognition all through the market.
It's main features may be understood with the following data:

A Typical Application
Making a simple 500 to 5000 watt inverter using IRF3205 mosfet.
A fifty watt inverter discussed in one of my previous posts can be easily turned into a massive 500 watt inverter by simply replacing its mosftes by the above type.
Refer to the following link for the required circuit diagram, just use the IRF3205 for the mosfets, 24-0-24V /30A transformer and 24V 200AH battery.
The inverter can be made to produce upto 5kva if the transformer voltage is increased to 50-0-50V/100amps.

Hello, my name is Richard. I am designing an inverter of 2kva working with 12-24v,how many irfp3205 should I use
Hello, 2 on each channel will be enough…
i have used irf 1404 and irf 1405,its so great and less rds on
also irfb4110 is great too but i didn't tried it yet.
Hellow! Swagatam,I have 12v/ 1200watts center tap transformer. How many IRF3205 transistors should be connected in parallel for the inverter to work?

hello hassan,
use 5 on each channel
It is nice to have a tech wizard in neighborhood, with a helpful heart.
Now my problem
1- I have a charger input 220v 10amp output 24vdc 1650watt with no automatic
circuit. I want to put an on off circuit on input side with 10 mins on 10 mins off cycle.
2- Can I get an ammeter design capable of measuring 150 amp dc?
3- How about on off circuit for generator, it stops when electricity is there
and self start when gone.
thanks
thanks!
1)for getting 10 min ON/OFF control you can use a 4060 IC with a relay, I have explained quite a few related circuits in this blog.
2) A high value ammeter value can be obtained by adding a calculated low value resistor across the terminals of any standard ammeter.
3) this can be done by simply using a relay….relay coil may be connected to a DC source with its contacts wired with the generator. Relay will respond to mains presence or absence thereby switching ON and OFF the generator corespondingly.
Dear sir i am using this mosfet (IRF3205) for my smps inverter in dc to dc converter section( push pull topology) but the problem is with 200 watt of load these mosfets are extremely hot. How can i prevent this problem. My gate voltage is nearly 5.7v.
Dear Sanasam, the mosfet driver stage may be faulty or wrongly designed in your circuit, otherwise the above mosfet will not heat up too much at 200 watts.
try increasing the gate voltage to 10V and check the results
