IRF520 MOSFET Explained / Description

IRF520 is a right MOSFET if you are looking to drive the output of an IC or from a platform like Arduino or Raspberry Pi. The maximum load this transistor can drive is 9.2A with the maximum load voltage of upto 100V. The transistor is also a high speed switching device due to which it can be used in any application where the switching speed is very important for example in UPS circuits. Moreover it can also drive a load of upto 37A in pulse mode.

On the other hand the max power dissipation of 60 watts also makes it ideal to use in audio amplifier circuit and in audio amplifier circuit stags.



Where We Can Use it & How to Use

IRF520 can be used in wide variety of circuits such as motor controller circuits, low current UPS, power supplies other than that it can also be used to drive other high power components such as relays and transistors etc. Due to low gate power requirements it can easily be used at the output of arduino, raspberry pi and variety of ICs and microcontrollers to drive high current loads. Beside the above uses it can also be used in audio amplifier circuits.



DC to DC converters

Applications that requires fast switching

Uninterruptible power supplies

Battery chargers

Battery management systems

Solar Applications

Motor Driver Circuits

Computer & telecommunication applications


How to Safely Long Run in a Circuit

To get long term performance use IRF520 atleast 20% below from its max ratings. The Maximum drain current is 9.2A thus do not drive load of more than 7.36A. The max drain to source voltage is 100V thus the load voltage should be under 80V. Gate to source voltage should be under ±20V and always store and operate the transistor in temperature above -55 Celsius and below +175 Celsius.
