IRLR3802TRPBF is a 3V single P-Channel Metal Oxide Semiconductor (MOSFET) transistor which is manufactured by International Rectifier. The device has an ultra-low RDS(on) and is suitable for systems requiring high performance and low power losses. It is offered in a low profile package that is compatible with most surface mount designs. It is available in quantities of either 10 or 25.

Application Field

The IRLR3802TRPBF MOSFET is primarily used as a load switch in high-performance applications. Its low on-resistance along with its fast switching speeds makes it suitable for high-speed applications, especially those that require output current filtration. It is also used in power converters, automotive systems, and battery management systems that require protection and/or current filtering.

Some other applications for the IRLR3802TRPBF MOSFET include motor control systems, power supplies, and even switching applications in low-noise systems. Due to its low on-resistance, it can also be used in high-power applications such as solar and wind energy systems.

Working Principle

MOSFETs such as the IRLR3802TRPBF are semiconductor devices that are used to control current flow. It is considered a four-terminal device, as it requires a voltage source, drain, source, and gate.

The IRLR3802TRPBF MOSFET works by employing an electric field effect, in which a gate voltage is applied to the gate to control the current through the drain-source terminals. The drain terminal is where the current enters the device, and the source terminal is where it exits. By applying or removing the gate voltage, the device can be switched on or off, allowing or preventing current from flowing through the device. When the voltage is applied to the gate, it attracts electrons in the channel and allows the current to flow freely. When the voltage is removed, electrons repel and the current is cut off.

The IRLR3802TRPBF MOSFET also has a high input impedance, meaning it can draw negligible current from the gate voltage supply even when conducting high currents. This makes it ideal for applications where low power losses are desired. In addition, the device is able to handle high voltages and can switch up to 30V. This makes it suitable for a wide variety of applications.
