But in reality you dont need that formula as it mainly has to do with the range wherein the FET DrainSource acts as a pure resistor. I noticed that the range is very low. Some people however have trouble reading a jrf1405 or do not know what to look for and in that case foing with TTL level FETs is a safe option.

The Rds on resistance is what will cause heating. Not an ideal choice, but a good one. datashret

Thanks — You are correct. The 20 Volt you probably saw in the datasheet, but that is the max voltage on the gate. Mar 30, 3 0. And a step up boost converter to supply the 5.

Whats about this, I have check in the datasheet and seems to work very well datasheer TTL levels even with a lot of Amps. The IRL is a logic level FET and putting 5 Volt on the gate should be enough to open it up, albeit that it has a drain source resistance of less than one ohm, though that depends a bit ir1f405 the current and the temperature. If bought per 20 it is 26 eurocts a piece.

The device will be either fully on or off as selected. I am getting almost 7V at the gate so no issues.

A logic level mosfet means that it is designed to turn on fully from the logic level of a microprocessor. To find out more, including how to control cookies, see here: Then you can find the current in the datasheet? It doesnt look dedicated to a steppermotor though, irff1405 to drive a rgular DC motor.

For a BC it is a bit on the edge. Jul 17, 22, 1, If it is not there, the gate will not get any voltage from the irff1405 V power source. I presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly.

The transistor may burnt. Nowadays more and more 3.

IRF1405 Relay/Switch

As Pete points out, sensing load current is non-trivial depending on drive mode: Learn how your comment data is processed. At 10 volt it is 4mohm and the fet can take 45 amp, but at 4. The circuit should be robust enough to support the load during a few minutes. Here’s the Yahoo home page: As the can be fed datasheett up to 18 Volt, it shouldnt be a big problem to use the to switch.


Excellent post, was very illuminating! You may also consider the IRLZ Also easier if you need to do high side switching.

The only conditions are it should have high switching speed so low rds on and high break down voltage. With regard to 9V and 5V input, I presume you mean supply voltage.


Well what an amazing article. Yes you can make it Ohm. They indeed can stand almost 7A, but only when sufficiently on or off. Email required Address never made public. How we connect irf mosfethere the problem is ….
