IRF520 MOSFET Datasheet, Pinout, Features & Applications

Hi Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to IRF520.

The IRF520 is an N-channel power MOSFET mainly used for switching and amplification purpose. It comes with a breakdown voltage of around 100V and a low gate threshold voltage is 4V, making it an ideal pick for microcontrollers applications.

I suggest you read this post all the way through as I’ll detail the complete Introduction to IRF520 covering datasheet, pinout, features, and applications.

Let’s get started.

Introduction to IRF520 MOSFET

• The IRF520 is an N-channel power MOSFET mainly used for switching and amplification purpose.
• It comes with three terminals named: gate, source, and drain and is available in the TO-220 package.
• It is important to note that the gate terminal is electrically insulated and contains no current and is normally called as Insulated Gate FET (IG-FET).

• As it’s an N-channel MOSFET so here major charge carriers are electrons as opposed to P-channel MOSFET where major carriers are holes.
• The movement of electrons is better than the movement of holes, making N-channel MOSFET better than P-channel MOSFET.
• Due to better movement of electrons, N-channel MOSFETs with high loads remain cool while P-channel MOSFETs turn hot in the presence of high loads.

• The major charge carriers i.e. electrons enter the channel through the source terminal while they exit the channel through the drain terminal. And the gate terminal controls the biasing of this MOSFET.
• This N-channel MOSFET comes with low on-state resistance of around 0.27 ohm, allowing it to dissipate less energy as heat and consequently increasing the efficiency of the device.
• IRF520 contains a low threshold voltage of around 4V which projects it can be turned on with 5V on the GPIO pins on the microcontroller.
• This chip comes with a decent switching speed, making it an ideal pick for DC-DC converter circuits.
• The continuous drain current (ID) of this device is 9.2A while the drain-to-source breakdown voltage is 100V. The Rise time is 30ns and the fall time is 20nS.
