About this product
IRF4905 is a P-channel HEXFET power MOSFET rated -55V and -74A, with a maximum on-resistance of about 0.02 Ω. Its low on-resistance suits high-side switching in motor drives, power distribution and load switching circuits. It comes in a through-hole TO-220 package for easy heatsinking.

How do I use the IRF4905 as a high-side switch?
Connect the source to the positive supply and the drain to the load, then pull the gate toward ground to turn it on. For the rated on-resistance the gate must be about 10V below the source, so a 3.3V or 5V logic output alone may not fully turn it on from a 12V supply. Use a gate driver or level-shifting stage in that case.
Does this MOSFET have a built-in diode?
Yes, it has an internal body diode between source and drain. For inductive loads such as motors or relays, add a flyback diode across the load as your circuit design requires, and check the datasheet for the exact diode characteristics.
