IRFZ34N – Infineon Technologies

I did connect a 10K from the gate to the ground. What I noticed is that when i disconnect datashee 19V supply, the serial monitor shows a steady 0 from the pot read from A0. Also the sine wave code is something I found out on one of the forums that was used to demo a bulb going dim and bright slowly. So the heater can be on during reset until the pin datxsheet pinMode is executed in setup. A better choice would be more like ohms, high enough to limit current but low enough to charge the input capacitance quickly as possible.

MarkT Brattain Member Posts: A thermistor is a type of variable resistor used to measure temperature. Normally the on-voltage will be about 3 times the threshold voltage being the point the device switches fully off. IRFZ34N getting too hot. I tried at reducing the resistor from 10K to Ohm. If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET.


In between those two the device can be half-on, meaning it may dissipate lots of power and get very hot – the region of operation you want to avoid.

The gate resitor is way too high.

But the thermistor isnt turning off. I measured a 2. Is the attached looking any better? It sends sine wave: Attached is the new circuit just a variation to datahseet prev, this time using a pot.

But that didnt make a difference. If that is a problem, a 10K. This is one of many useful ones. The test code I used is here. The behavior that you describe sounds like what jremington mentioned irfz34m reply 7.

I read serial values and can see that the pot is working. Triple check the wiring and post a circuit diagram hand drawn, not Fritzing.

Is your printer bed rotating? Screen Shot at Please point out what you are calling a thermistor on your diagram. Some people get confused by the threshold voltage – this is the voltage the device switches fully off, not on.

The key specification is the value of Vgs quoted in the on-resistance section. Here is the code, Code: But when I connect the 19V, the values start floating wildly, and thats probably why the thermistor started smoking before I unplugged. Ok, once again, thanks for helping out an electrically challenged person. I am PWMing the pin 3 of the nano. Agree about the gate resistor. I am using the attached circuit to heat up the 3D printer bed.

The thermistor 25W 5. As mentioned above, the schematic shows the MOSFET wired backwards, which can’t work the heater should be on all the time due to the body diode.

I need to study more.
