IRFA MOSFET Datasheet pdf – Equivalent. Cross Reference Search

Good luck with your project. For example, when used with a high frequency PWM and high amps, careful testing must be done, because high frequency means more time spent dagasheet the linear zone, and these parts can quickly get hot and burn, differently of TO parts, that can also burn, but only after some minutes of overheating. Backyard controller design Eric’s Arcana and RiderX.

That 52 mOhms at 2. This site uses Akismet to reduce spam.

fatasheet What kind of lamp is it? Now you want to put current through a coil. The Vce in saturation is about 0. So the currents you are quoting are with a full supply voltage across the FET for a very short time. It shows the same behaviour when I use 3.


IRF530A MOSFET. Datasheet pdf. Equivalent

It start switching on at around 3V and it seems to be quite wide open at 4,5V. If you come up with an idea I would be happy to hear it. For the IRF it is even worse. The gate source resistor is purely to make a predefined state and to avoid the entrance to float I do not know the PIC18F that well, but what is important is the Output voltage it has on its pins.

IRFA – Fairchild Semiconductor – PCB Footprint & Symbol Download

Im actualy pondering the same question as Legolas. Realise though that it is an inverting circuit.

I will try source a IRL At 5V volt on the gate, the IRF will pass something around 4. Thank you for this very good explanation.

However it has a very low Rdson. Perhaps it is a lose wire or something. However I advise you against building that yourself as they are rather cheap if you just buy them: Another thing to beware of in datasheets is Vthresh threshhold voltage.

Nowadays more and more 3. You could consider the FQP27P Dwtasheet the and will be more efficient with this circuit. But suppose the FET you choose has 0. Not an ideal choice, but a good one. The datasheet indicates max Vgs 4V but the curve shows that at 5V the mosfet can deliver current way above my requirement.


R1 ir5f30a just there to limit the current through the gat, coming from a microcontroller pin. I will use Arduino to dim the power acording to inputs from handlebar. Using the transistor to drive the gate with higher voltage solved the problem.

Advanced Power MOSFET

I am using this converter: Then indeed the FET will open but it cannot go above 5Volt at the source, because then it will close again as the VGStsh is around So if yr gate voltage is 5Volt, your source voltage will never be above that. Sadly though it can only dissipate some 80 Watts There is the MTB60N05HD L that does 60 amps 50 Volt and Amps beware of the somewhat high input capacutance, bu thta does not need to be a huge problem in simple switching also you may consider browsing through this guide.

The is somewhat better: Was that the same as for the mosfet? IRFZ44, and you want to switch somewhat higher voltages i.
