IRLZ34N MOSFET Explained / Description:

IRLZ34N is another good logic level N channel MOSFET designed to use in a wide variety of applications such as commercial and industrial other than that it can also be used in educational and hobbyist projects. The MOSFET has many features which are as follows.


Logic Level Gate Drive:

The MOSFET has logic level gate drive means it has low voltage derived capability due to which it can directly be derived from ICs, microcontrollers, and electronic platforms such as Arduino and Raspberry Pi.


Fast Switching:

It has fast switching capability which makes it ideal to use in applications which require nano second switching.


Fully Avalanche Rated:

It is fully avalanche rated which means it will perform stable even when its drain to source voltage exceeds its limit.


Low RDS(on)

Its low RDS(on) makes it energy efficient due to which less heat is generated during the operation which results in less power wastage.


Max Operating Voltage of 175°C

The maximum operating temperature of 175°C makes it stable on high temperatures where the other low temperature MOSFET fails.

Other features are dynamic dv/dt rating, enhancement mode etc.


Where and How to Use:

IRLZ34N can be used in many applications from commercial to educational such as automotive, portable and battery operated applications, solar etc. Other than that it can also be used in audio amplifiers.

Safe Operating Guidelines / Absolute Maximum Ratings:

To safely operate the transistor follow the guidelines below to get long term performance.

  1. Do not use the MOSFET to its absolute max ratings and always stay 20% below from these ratings.
  2. Max continous drain current is 30A therefore do not drive load of more than 24A.
  3. Always use a proper heatsink.
  4. Maximum drain to source voltage is 55V therefore do not drive load of more than 44V.
  5. Store or operate the MOSFET at temperature between -55 °C to +175 °C.
