IRF1010E: The Ultimate Guide

Generally, there are two types of MOSFET; N-channel MOSFET and P-channel MOSFET, working in either enhancement mode or depletion mode. N-channel MOSFETs have electrons flow as charge carriers. Conversely, P-channel MOSFETs have holes as charge carriers. IRF1010E is an example of an N-channel MOSFET type. In today's post, we'll give you a detailed guide on IRF1010E by discussing its operation, pin configuration, applications, and features.  

What is IRF1010E?


IRF1010E is an N-channel power MOSFET commonly applicable in high-speed switching applications. And unlike a bipolar junction transistor, a current-controlled electric component, IRF1010E is a voltage-controlled device. It also comes with terminals on the emitter, collector, and base.

As for its operation, the IRF1010E working principle involves regulating the current and voltage between the source and drain terminals. Further, it uses a MOS capacitor, a key component in its functionality.  

Pin Configuration of IRF1010E


An IRF1010E chip contains three terminals which are gate, source, and drain terminals.

Pin1 / Gate terminal; It biases the device. Often, triggering it turns on the MOSFET.

Pin2 / Drain terminal; It acts as an exit channel for electrons and has the load connected to it.

Pin3 / Source terminal; It's the channel that allows the entry of electrons and links to the ground.

Always check on the pinout of the IRF1010E equivalent because their pin configuration might differ from the IRF1010E pinout.  

How to use IRF1010E


We will use an IRF1010E MOSFET in a circuit to help illustrate how IRF1010E operates.

IRF1010E in the circuit above functions as a simple switching device.

  • We also have the load represented by a small motor.
  • Further, the control unit provides the trigger that turns ON the MOSFET. Using a microcontroller here isn't advisable because they can't produce voltages more than +5V.
  • In addition, we have the source at the ground line, and the power source is from a +12V battery.
  • V1 is the control unit trigger voltage, and V2 is the gate voltage.
  • Resistors R2 and R1 make up a voltage divider circuit that gives a required voltage at the gate terminal. For that reason, their choice depends on MOSFET gate threshold voltage and V1.

Let's use an example here;

For instance, we can have a control unit providing pulses +12 volts. Then, we'll need another gate voltage of 10V to help in completely turning on IRF1010E MOSFET.


V1 = +12V

V2 = +10V

We can have R1 as 200Ω, 400Ω, or 2K pairing up with R2 that has 1KΩ, 2KΩ or 10KΩ respectively. Each resistor set should give an exact +10V at the MOSFET gate terminal.

The current draw from a MOSFET is negligible. Therefore, you shouldn't have that consideration when choosing a resistor set.  

Circuit operation explained 


  • Under normal circumstances, the MOSFET circuit stays OFF because there's no Gate voltage. Consequently, a complete Vcc will appear across the OFF MOSFET. Similarly, the drain current will be zero thus, contributing to an idle motor.
  • But, if a control unit provides some voltage pulses, the circuit will gain a gate voltage. In turn, the MOSFET will switch ON and start working. Then, there will also be a drain current flowing through your motor, making it start rotating.
  • If you start having a common control unit output, your gate voltage will also run low. As such, the MOSFET will go OFF as soon as the gate voltage goes below the threshold voltage. Subsequently, the drain current becomes zero and stops flowing through the motor, preventing its rotation.

We can conclude from the above explanation that IRF1010E MOSFET is a switching device triggered by a control unit.

Note; Our circuit above represents a testing circuit. If you need an application circuit, remember to include other components like a flyback diode and heatsink.
