Vishay – MOSFETs – IRF, SiHF – Power MOSFET

Transistor is damaged, and conduct when there is no voltage at the gate; 2. There are two possibilities: Here’s the sketch, and the schematic for what I have setup: Magician Faraday Member Posts: But for LED, or low current application it’s really doesn’t matter.

Its rds is 6ohm max and if you look at the id vs. That page can be found here: Also, 10k series is way too much resistance for a LED driven by 12 Volts.

Magician on Mar 04, Vds chart it is even smaller for a Typical 2n Schema of my device is. So people arguing for its high rds are reading the spec without understanding it.

IRF520, SiHF520 product information

While prototyping the project, I removed the diode, replaced the motor with an LED, using 12v external power, and gave it a 10k pull-down resistor.

It only worked due to the low load being switched. The real purpose of my topic was to find the difference between using the motor in the Arduino book, and an LED. Irf5x0 is actually a poor choice here.

Now I actually want to implement it in a project that involves flashing an array of LEDs. Sign up using Facebook. MarkT Brattain Member Posts: That’s all I was asking. If the LED is on even when you ground the gate, it’s possible that you confused source and drain.

The motor just stays on constantly. If anything they are already too big. So does that mean that the gate needs 10v applied to it for it to switch correctly?

I don’t think anyone actually realized that. Sign up using Iff520 and Password. I successfully managed to build that project and it worked perfect.
