What is the maxium power we can get out of the IRF On the datasheet it states that the maxium voltage can be v and the maxium permissable amperage is 5.

Does this mean I can get 5. The datasheet just does not indicate the power. Thanks a lot for your help. Time duration spans from DC in steps dataeheet ms or us.

The maximum current ant voltage may simultaneously only dataaheet applied during very short time us range. Note that the graphs are for a starting temperature of 25 degrees. So when temperature at the beginning of a large power transient is higher, you have to reduce the peak power during certain time. That means less current, voltage or time duration. The maximum power you can generate into a load depends on the circuit. When you use this mosfet as a fast switch, you don’t have inrush current peaks and apply the correct drive, theoretically you can switch a W load.

The mosfet itself has to dissipate MORE then 0. The reason for that is that at higher junction temperature, Rdson increases, xatasheet you have to calculate with a higher datasneet for Rdson. Rdson versus temperature is mostly given in a graph also. I would reserve some margin and not push the component to the limits.

All transistors mosfets meeting the search criteria “CEP703AL-G/CEO7030L”

Power dissipation for the device, not the load is given under the assumption that the temperature of the case of the fet is 25 degrees. As this is normally not the case, you have to reduce this also, based on your heat sink. Saludos y mucha suerte con su circuito. We have to calculate how many IRF we’d need to operate a watt motor via a pwm circuit. We see that when the Mosfet IRF is pulsed it can be used to transport higher currents.

In fact in the datasheet it states 48 amps!!!!!!!!!!!!!!!!!!!! That seems impossible, can it be? We are starting to look at more useful circuits which seem to present many more difficulties than the circuits we’ve done up to now.

Any help will be most appreciated.

It states 20amps when pulsed. This avoids the high inrush current what you get when you apply V directly to the motor.


When paralleling mosfets, it is best to give each mosfet its own gate resistor to have better current sharing during turn-on and turn-off. You also have to find a good balance between the number of mosfets, switching frequency and heat sink requirements. Many mosfets need a more powerfull driver to avoid significant switching loss. Very fast switching may result is more EMC problems. I don’t know what sort of load the motor is driving, but when there is a change on jamming or other circumstance that may result in high current, you may add a current measuring circuit.


Based on the measured current, you can control the PWM. It will results in higher component cost, but you may consider EMC filtering between the power stage and the motor to avoid additional costs because of inconvenient EMC test results.

It also enables you to make the current waveform less dependent on motor type and wiring in case of long cables between power stage and motor.
