IRLB3034 Transistor Explained / Description:

Today we are going to discuss another interesting MOSFET IRFB3034 which is an N channel MOSFET available in TO-220AB package. The primary applications of the transistor are fast switching, UPS circuits, DC Motor control circuits, switch mode power supply circuitry, high frequency circuits, hard switched circuits etc. But it is not only limited to these applications and can be used in wide variety of other applications which falls under its ratings. There are many features and benefit of this transistor which are as follow:


High Speed Switching Capability

The transistor is capable to deliver high switching speed which makes it ideal to use in design or applications which requires high speed switching.


High Continuous Drain Current

 Another good feature or benefit of this transistor is its high continuous drain current which makes it a crucial component where the designer want to drive a high current load of upto 195A.


High Pulsed Drain Current Ratings

The pulsed drain current value of the MOSFET is very high. The maximum pulsed drain current of the transistor is 1372A which is also very interesting.

Very Low RDS(on)

The very low RDS(on) or the maximum drain to source resistance in active state of the transistor is also very low due to which the transistor dissipate less heat in active state or when driving the load.


Optimized for Logic Level Drive

Another benefit or good feature of the MOSFET is that it is optimized for logic level drive means it can directly be operated from ICs, microcontrollers and electronic platforms like Arduino, Raspberry Pi etc.

Other features are Improved dynamic dV/dt ratings, improved avalanche, improved gate, avalanche SOA etc.


Where We Can Use it & How to Use:

Although IRLB3034 is primarily designed to use for motor control circuits, fast switching circuits, switch mode power supplies, high frequency circuits etc. but it can also be used in wide variety of other applications such as different types of power supplies, battery charger circuits etc.



Uninterruptible Power Supplies

Safe Operating Guidelines / Absolute Maximum Ratings:

For safe operating the device follow these guidelines, first of all the transistor should not be used on its absolute maximum ratings and always stay 20% below from its max ratings. The maximum continuous drain current is 195A therefore do not drive load of more than 156A, the maximum drain to source voltage is 40V therefore do not drive load of more than 32V. Use a suitable heatsink with the transistor and always store or operate the transistor at temperature above -55 °C and below +175 °C.
