Mosfet not heating bed
WebMOSFET Board. The MOSFET Board is one of the most important safety mods for the Anet A8. When the heated bed warms up, it draws a large amount of current through a small connector on the board. Since this connector isn’t rated for the power it pulls, it will inevitably melt the terminal and when it does, there is a decent chance it can start ... WebSep 7, 2015 · The R and C for a slower slew-rate to the gate will make the mosfet get hot. Only the R to protect the Arduino is good, use 220 or 470 ohm or so. You need a protection diode from mosfet drain to 12V, because the heater might have some inductance. One of the most complex subjects is grounding. With 7.5A, the ground currents can be a big issue.

The MOSFET doesn't have to dissipate 150 watts. The heating pad does that. The mosfet only needs to flow the 12.5 amps when heater is on, and then block the 12 volts when you want the heater off. The Rds (resistance) of the mosfet could typically be 31 mohm (0.031 ohms) when on.
