IRFZ46 Datasheet PDF ( Pinout ) – Power MOSFET

A variable resistor to safely handle your load is just too expensive. Are they DC brushless fans? I think that would work unless the fans are too big.

Check the specs again. Pulsed Diode Forward Current a. Vishay Intertechnology Electronic Components Datasheet.

Or a darlington using a 2N with another smaller transistor if you already have these laying around. V DS Temperature Coefficient. My aim is to be able to control the speeds of all of the fans at the same time. You May Also Like: Help with slowing fans Posted by whoyah in forum: Jul 6, 9. Your name dxtasheet email address: The op-amp watches the voltage drop across a shunt resistor and compares it to a reference voltage set by you with an inexpensive variable resistor.


Jul 6, 7. Electro Monkey likes this. The TO package is universally preferred for all commercial-industrial applications at power dissipation levels to approximately dataasheet W.

Hi, I am trying to build the circuit shown in this link: Need help with proper battery selection please. Drain-Source Body Diode Characteristics. Datasheer low thermal resistance and low package cost of the TO contribute to its wide acceptance throughout the industry.

Single Pulse Avalanche Energy b. Here is the data sheet: Sep 9, 15, 5, Oct 15, 5, 1, Jul 6, 5.

Jul 2, 8 0. Continuous Drain Current e.


The low thermal resistance. Or build a variable LM supply. If you need more current, you could make an op-amp controlled, constant current supply with a MOSFET or two on a big heat sink. Repetitive rating; pulse width limited by maximum junction temperature see fig. Continuous Source-Drain Diode Current. Jul 6, 6.

Soldering Recommendations Peak Temperature d. Zero Datadheet Voltage Drain Current. They don’t work with Datasheeh Second. Do you already have an account?


You need to know how much current each fan will require though to ensure you aren’t overloading the variable voltage circuit with multiple fans. These linear solutions are functionally the same as your resistor, but can handle much higher currents with ease and precision at a lower cost.

How many wires on the fan? The TO package is universally preferred for all. Body Diode Reverse Recovery Charge. Quote of the day.
