The post explains the main features datasheet of high current N-Channel mosfet IRFP2907 which is rated to handle up to a staggering 209 amps of continuous current at a reasonably massive 75 volts.
High Current Specs
With the advent of mosfets, switching huge power through compact packages has become particularly feasible.
Take for example the proposed high current mosfet IRFP2907 (has no relation to 2N2907) which could be used for switching currents exceeding 200 amps, exclusively suitable for wind turbine generators. application
Although this device is designed specifically for automotive applications, the extreme range of this device can be effectively employed for many other applications such as inverters, wind turbines, soar inverters etc.
Precisely, this N-Channel device would be ideally suited for wind turbine inverter applications since this application incorporates alternators which is an automotive component.
Main Specifications and Features
Let's learn about the main features of the mosfet IRFP2907
- Advanced Process Technology: ensures a rugged foolproof design and operation parameters.
- Ultra Low On-Resistance: allows optimal delivery of the source current across the load thereby enhancing the overall efficiency of the system.
- Dynamic dv/dt Rating: makes the unit extremely desirable with high power critical systems.
- 175°C Operating Temperature: this extreme range allows better sustaining, and consistency even under stressful operating conditions
- Fast Switching: Makes the device specifically suitable for rapid high current switching applications without the fear of device breakdown yet with maximum efficiency.
- Repetitive Avalanche Allowed up to Tjmax: Avalanche current is no more an issue with this device which is well guarded to make it completely failproof even under worst case scenarios.
Technical Datasheet
The Datasheet of the High Current Mosfet IRFP2907 may be understood with the following points:
- Extremely Low RDS(on) = Typically around 4.5 milliOhm, that's almost zero resistance across the drain and the source terminals when the device is fully saturated.
- Saturating Voltage = The saturating voltage VGS is around 10V which may be exceeded to not more than 20V. Applying this range of voltage across the gate and the source terminals would allow full saturation and almost zero resistance across the drain/source terminals.
- High Switching Current: With the above parameters applied, the maximum allowable current across the drain and the source terminals would be anything up to 200 amps....that's huge.
- Breakdown Voltage = It should not be exceeded preferably above 70 volts. This is applied across the drain and the source with a load in series at current levels that may exceed the 200 amp mark, as explained above.
Thanks for sharing Sir.
So how many pieces of this mosfet do I need to make my 2000 watts inverter?
Thanks a lot
Aminu, you can use 3 or 4 MOSFETs in parallel to handle 2000 watts comfortably, but remember MOSFETs alone will not help, you will also have to upgrade the transformer and the battery appropriately.
very nice indeed! can i use this power transistor for 5000w inverter?
Yes definitely, you can use it.
thanks
Hi Swagatam!
I’m designing a solar inverter and i’m stuck with the current control…
I applied 30A continuosly in it (heatsinked) and got further 150 C…
The datasheet lies, there is no way it can handle +200Amps
I thought that I will only need four for a H bridge driving 100A at 48V, big mistake.
Now i’m gonna put 24 of them (6 in each side of the H bridge)
Do you know what’s the PRACTICAL limit of them?
Or should I go to SOT-247?
Thanks!
Hi Saulo, the datasheet is not wrong. It is only suggesting that the mosfet has the capability to handle 200 amps provided its case temperature is not allowed to rise above 30 degrees Celsius. If you can use water cooling and keep the device temperature at a constant 30 degrees C then it may be possible to use the max figures.
24 are too many according to me, just 4 or 5 may be enough to handle 30 amp provide they are mounted large heatsink with fan cooling.
Hola Swagatam, necesito ayuda para fabricar un circuido inversor 12v a 220v 1000w, con este transistor, necesito esquema para IRFP2907 etapa de potencia. ( tengo un transformador de 1000w y un oscilador ).
Hi Cristian, You can use the mentioned MOSFET just as any other MOSFET, no need of any special drivers. What is transformer configuration, is it a center tap or a two wire type?
Thanks for replying sir.
The irfp2907 is not available in my area. So I decided to use irf3205 which is very common here.
And to upgrade the transformer current I need your help.
I don’t know if the transformer made of aluminium wire will handle 2000 watts, if it can then what is the thickness of the wire for both primary and secondary winding.
Thanks
Hi Aminu,
Yes IR3205 is a good option.
I don’t think aluminum wire can be used to build efficient transformers with a 2000 watt capacity, you will need a super enameled copper wire for that.
hi sir can i replace a chinise mosfet hy1906 with the available mosfet like irf3205 nedd help please??
Hi Luis, you can do it, but make sure the voltage and current specs of your mosfet is not less than the original mosfet.
If you use two 2907 with a center tapped transformer & big heat sink, can it tolerate or replace arrangements of 50N06 ie each 2907 =6, 50N06, please highlight.
what is the specifications of 50N06?? if 2907 is 6 times higher than 50N06 then yes your assumption may be correct, it can be replaced with a single 2907 having a calculated large heatsink.
Hello sir, can I make a circuit for motor reverse and forward rotation for few time base
Hi Kanji, yes you can by using a 4060 IC
Hi sir, can I use IRFP2907 in place of hy1906 or other suggestions
Hi Shahnawaz, please check the datasheets of the two fets and check what voltage and current these are rated for…and then you can judge yourself whether or not these are interchangeable.
can i use this mosfet (IRFP2907) for replacement?
Thanks sir
yes the specs match, so it can be tried
Hi Sir Swagatam,
I have a busted GTI. I would like to know if i can replace the mosfet with another brand of N-Channel?
original Mosfets:
HY1906
65V/130A
Hi OLiver, yes that can be done.
