substitute of a mosfet?? Answered

I'm in 6th sem EC and my group is making an project on auto intensity controlled street lights.
In the circuit a irf520 mosfet is required which we are not having. so if any other transistor could be used in place of that, please tell.

Only another mosfet, it goes this way I look-up and give you one.

Then you say you are not having.

I look-up another and give you that one,

But you are not having !

i stop now....

International Rectifier IRF520 available from Jameco for $0.69 is a 100V 10A @ 10Vgs not really good for streetlights.

A replacement is a Vishay SiHF520 same spec also in a TO-220 package.

Find the datasheet, and see what specs the IRF520 has, and if you have a junk bin with old mosfets or something, look up all their datasheets and pick the closest matching one to the IRF520. Being a power MOSFET, my guess is that you are using it wor a switching application, where things like on state resistance, Vds rating, gate saturation voltage, and rise/fall times are most important.

It's simple enough to look up the specs. One then tediously searches for a suitable replacement, or uses one of the many vendor site helpers to determine a suitable replacement.

I'd also like to remind you that as a student, it's your responsibility to your own footwork.
