IRF100B202 is a single N-channel enhancement mode lateral MOSFET, suitable for high-frequency switching application. This power MOSFET has a high-current density and can easily dissipates heat, because of its small size and low gate threshold voltage. It requires very low gate drive and presents high efficiency, no free wheeling diode is needed. Moreover, IRF100B202 has an immunity to secondary breakdown, making it an efficient component in applications including DC to DC conversion, lighting, and motor control.

Application Field

IRF100B202 is an ideal component for use in applications where low voltage and low capacitance logic levels are required. It is ideal for high frequency switching and low input capacitance switching applications, but also for any device that needs switching rapidly, such as high-frequency digital-to-analog converters, ADSL modems, etc. IRF100B202 is also useful in a wide range of other applications, such as power supply, UPS, SMPS, and power management.

IRF100B202 is very suitable for high frequency switching applications, because of its high frequency performance and high switching speed, as well as its low input capacitance. It can be used in both DC and AC applications, such as lighting and motor control. Furthermore, it is compatible with microprocessor motherboard designs, because it is easy to interface.

Working Principle

IRF100B202 is also known as a single N-channel enhancement mode lateral MOSFET (metal-oxide-semiconductor field-effect transistor). Its working principle is based on the injection of a charge from the metal gate into the substrate. This is followed by an increase in the potential barrier between the metal gate and the substrate. As the potential barrier increases, more charge carriers (electrons for p-type transistors, and holes for n-type transistors) are driven out of the substrate and into the channel of the transistor.

When a p-type MOSFET is in an off state, there is an absence of current flow through the channel. In this situation, the potential barrier is high and the gate voltage must be increased to reduce it and allow current to pass through the channel. However, when a n-type MOSFET is in an off state, current will flow through the channel, even though the gate voltage remains low. This is because, with n-type transistors, the electrons are strongly attracted to the metal gate, reducing the potential barrier, allowing current to flow.

In an on state, the gate voltage reaches a level that is lower than the threshold voltage, which then causes a significant reduction of the potential barrier and an increase in the number of charge carriers. Therefore, current can easily pass through the channel and the conducting circuit is completed.

The properties of IRF100B202 make it an ideal component for a variety of applications. Its switching speed and current capacity make it suitable for high frequency applications. It is also very suitable for low input capacitance applications because of its high voltage and low gate threshold voltage.

In addition, with its relatively low on-resistance and low power consumption, it can provide high efficiency in most applications. Furthermore, IRF100B202 is also robust and offers excellent immunity to secondary breakdown and other stresses typically found in power supply applications.
