IRF MOSFET Datasheet pdf – Equivalent. Cross Reference Search

Thanks Pancake plus karma I got it to work I think I confused gain drain and source on the mosfet like a newb. How many do you need? I have a IRF connected to a 5V micro. Well I looked at the data sheet and basically it doesn’t say anything about the tab or hell i didnt know to call it a tab because it doesn’t label it as that etc etc.

Home Questions Tags Users Unanswered. There are plenty of such FETs. I’ve posted this circuit more than once — Go To Reply 14 For The Latest Version It’s not optimized for yeah, you know, well every damn thingso it offends snarky ol’ Mr.

Hi, Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png or pdf? Drive-by” that’s somebody else. That is a great question TonyStewart.


For 6A and without heatsink, aim for 15 mOhms or lower. Threshold voltage is the Vgs at which is begins to conduct just a little bit, you need way more to have good switching. How come this is happening? Now, it’s true that 4 volts is worst-case, and you are surely doing better than this, but it’s the heart of the problem. More parts and slower switching.

IRF530, SiHF530 product information

And is “on” when the Arduino is off, and could be “on” during bootup. AT the least they should rename it like Vgs Cut-Off or something that makes you think about it a different way. While others have adequately answered the question, I thought I’d approach it from another perspective, in order to give you some insight as to how to read data sheets. moseft

Now look at figure 3. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyirrf530 our Terms of Service. Use 12V to drive the gate 1k pullup, 1k down divider from 24V and shutoff with an additional NPN inverter to shut off gate.


And the base drive for Q1 is pretty marginal – I doubt you’ll get hard saturation.

And that 22k needs to be 1k to lower switching losses. The trace mostet on a PCB and very short, with only a pull down resistor on the gate:. Notice that at the rated voltage, the drain current will only be uA. Go back to your IRF data sheet, and look at the Vgs th rating of 2 to 4 volts. High side switching with a P-channel mosfet is another option, but more complicated. It just kept the lights on no matter what. This allows the temperature to stabilize, rather than running away.

If your circuit is in ir530 aluminium case this can also be your heatsink.

If you can tell me what page and what irf503 of info says it on the datasheet maybe i can learn where to look next time. When I set the pin to high, the mosfet gets very hot.

IRF getting very hot Ask Question.

Therefore it will not conduct fully and act as a resistor. And that the posted circuit inverts change your code.
