Hi, I am trying to test the following power MOSFET using digital multimeter. http://www.fairchildsemi.com/ds/FD%2FFDL100N50F.pdf I am using the following way to do this http://in.answers.yahoo.com/question/index?qid=20061126230136AA6Blij But this MOSFET is showing anything. Its a new part. I tried another MOSFET (IRF540) and the test worked fine. I think that FDL100N50F has large...

Hello, I've discovered logic-level mosfets, and am using an Arduino to drive a small 12VDC (about an amp or so) pump motor with PWM, using an IRLZ34N as the power mosfet. Would a mosfet-driver be recommended to switch that mosfet on and off more quickly? Or is a logic-level mosfet already designed to efficiently turn on and off with the weak logic level signal? Thanks, Michael

I'm trying to drive a big LED (3W) with a MOSFET. Eventually I want to drive it with an Arduino but so far I'm failing to get the right numbers in my test circuit. My test circuit is like this: +5 | [R1] (8 Ohms) | D G -[R2]--- JUMPER S | LED | GND I can connect the jumper cable to +5V or ground and it switches on/off as expected. My MOSFET is one of th...

I have a 75332P MOSFET on a cordless drill controller heatsink. I guess it's part of a pulse width modulator. The drain (flange) connects directly to one of the battery terminals. Does the MOSFET drain go directly to the battery minus/ground terminal? Or does it go to the battery plus terminal? Thanks. -- My application... I'm desperately trying to develop a better inline ...

Guys: I'm an ME working on a project where I must switch voltage to a small coil = on and off at a fairly high frequency (around 25 kHz) with a MOSFET transis= tor. The DC resistance of the coil is very low (about 1 ohm), but the impe= dance is much higher because of the frequency (about 100 ohms). I'm switch= ing 24 Vdc. Should I specify the max. pulsed current of the transistor based...

For a project I noticed my Arduino PWM pump controller (basically just an Arduino, MOSFET, and protection diode) was behaving oddly, so I powered the pump directly from the 12V power supply, turning it off and on as needed manually. I looked more closely at my breadboard, and noticed the drain and source were touching. The circuit had been running for a few minutes this way. Did I damage my...

Hi, Can anyone give me some directions on how to develop a circuit simulator from scratch. I need to develop a simple spice compatible simulator,that can read in spice netlists. I will be using C++ to code the simulator. I need to support only simple R,L,C, diode and mosfet devices and DC,AC and transient analyses. I would be using the Ebbers - Moll models. The problem is that I could not ...
