MOSFET Transistor? Answered

Hey Instructables. I am working on a project requiring some MOSFETs but they have to be smaller than the Radioshack IRF510's (http://www.radioshack.com/product/index.jsp?productId=2062618). I think I found some ones that are smaller (http://www.jameco.com/1/1/195-bs170-transistor-bs170-n-channel-mosfet-60v-92.html), but do they have the same functionality? What I mean is, will they work the same way? I believe they will, since they are both labeled as N-Channel MOSFET Transistors, but its always good to check. Thanks in advance!

The TO-220 Large IRF510 is a 60 Volt  3 Amp  MAX
The TO-92 a Small BS170  is a 60 Volt  1/2 Amp = 500 ma MAX

So if the load you want to drive is under 40 volts and works under 400 milliamps
Your small mosfet will do !

Thanks everyone!

To one point yes however the IRF510 is a 50 watt and the BS170 is a 350 millwatt.
If you need the 50 watts the BS170 is way under powered.
