概述

Description

The IRLB8748PBF is a N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) designed for high-efficiency switching applications. It features a low on-resistance (RDS(on)), typically around 8 mΩ at a gate-source voltage of 10V, which allows for reduced power losses and improved thermal performance. With a maximum drain-source voltage (VDS) of 30V and a continuous drain current (ID) of 78A, it is suitable for use in power management, DC-DC converters, and motor control applications.
The device is housed in a TO-220 package, facilitating effective heat dissipation. It is also RoHS compliant, making it environmentally friendly. The IRLB8748PBF's high-speed switching capabilities and robust performance make it a popular choice among engineers for various electronic designs. Careful thermal management and proper circuit design are essential to maximize its performance.

Package

The IRLB8748PBF is typically available in a TO-220 package type.

Pinout

The IRLB8748PBF is an N-channel MOSFET with a total of 3 pins. The pin configuration is as follows:
1. Gate (G): This pin controls the MOSFET's switching operation. A voltage applied to the gate allows current to flow between the drain and source.

2. Drain (D): This is the terminal through which the main current flows out of the MOSFET when it is in the "on" state.
3. Source (S): This terminal is the input for the current that flows into the MOSFET from the load.
The IRLB8748PBF is commonly used in applications such as power management, DC-DC converters, and motor control due to its low on-resistance and high-speed switching capabilities. It is available in a TO-220 package, making it suitable for heat dissipation in high-power applications.
