I'm using three IRLB8721 MOSFETs to power my LED strip. Through an ESP-12F I'm delivering 3.3V to each gate, which should bring me a 12V output, I think. But this doesn't work, I only get 5.8V - 7.6V (roughly). Any tips on what I did wrong? Did I use the wrong parts maybe (that would be strange since I followed a tutorial where it works)?

Here's the datasheet

[Here's the wiring plan][2]

I think I used the wrong mosfet/transistor, used another one. Now it works

    \$\begingroup\$ How much current are you trying to pass through the transistors? \$\endgroup\$ – Elliot Alderson Jun 28 at 17:50

    \$\begingroup\$ Yes, figure 1. Depends on the load current. What current do you push? \$\endgroup\$ – winny Jun 28 at 18:28

    \$\begingroup\$ "What transistor, do you mean the mosfet?" - MOSFETs are transistors. That's what the "T" in "MOSFET" stands for ;) \$\endgroup\$ – marcelm Jun 28 at 18:49

    \$\begingroup\$ You are constantly avoiding the question. Current! How much? \$\endgroup\$ – winny Jun 28 at 20:57

    \$\begingroup\$ Please be aware that as an engineer, it’s a very dangerous path to change something at random, notice it starts functioning and leave it at that without understanding why. \$\endgroup\$ – winny Jun 29 at 15:38
