These work pretty fantastic with 3.3v logic or 5v logic. Great little mosfet with high amp rating.

I got these for an Arduino LED PWM driver circuit. From the datasheet, the 5v the arduino provides should be sufficiently capable to turn the mosfet on above the amperage i am going to be pulling) hooking them to the arduino does nothing. They only heat up and let out the magic smoke. I am using 12v to the drain to source voltage, and the amperage b3ing put theough is around an ampNo matter what voltage I drive the gate at, the gate doesn't turn on, and only uncontrollably heats up. Mosfet gate also pulls around 200mA, and not the 250 microamps the data sheet specifies.Absolute trash. I tested a different suppliers IRFZ44N that my uni had, and they worked the first time.

All working! Although the packaging was slightly lacking in protection. I made a test rig and tested them after straightening a few legs and they are all good, so I'm happy with that.

I think that's a quality thing where the "off state" would be closer to 0 if it was more expensive but considering they're like 50cents each I guess it's alright. Also thresholds probably I just don't know enough regarding the data sheet to explain the values I got.It took me a bit to figure out how to wire these things as it's almost backwards to me how they work.But I am using it as an on/off power switch for a sensor that is fed by a ~5V source. So my microcontroller pin that's connected to the gate outputs a high of ~3.3V and then the drain is connected to my sensor's ground, source is the 5V ground. In my case "on" was 5.26V and then the off state was 0.5 or so takes a little bit of time to get there i.e. not immediate but yeah.So I think this works, I was aiming for an "absolutely off" deal but I can look into that more. As my case is a battery powered device.

Be aware that even though the gate threshold is listed as 2-4 V, this is NOT a logic-level MOSFET, and it will burn up with a high load without using a higher voltage on the gate. If you need something to use directly on a microcontroller, get something that starts with "IRL" (not IRF)

All of these tested within the specs that I'd expect based on International's datasheet for this model.

They are what they say they are, and cheap. I accidentally bought 2 of these kits but it's a common enough mosfet to use everywhere. I have only tested them on 5v logic but i assume 3v3 won't be an issue
