IRL3803STRR

The IRL3803STRR is a N-channel Power MOSFET, developed by Infineon, which offers excellent switching characteristics, a low On-resistance, and low gate charge. It is specifically designed for use in synchronous buck The IRL3803STRR is used in medium- to high-power applications, such as LED lighting, photovoltaic systems, and industrial motor control. This MOSFET has a low drain-to-source saturation voltage of 1.2V and low gate-charge characteristics, making it ideal for switching applications that require efficient power control.

The IRL3803STRR has a drain-source voltage (VDS) of 30V, a drain-source current (ID) rating of 10A, and a maximum power dissipation (PD) of 11W. It is a “low-threshold” MOSFET, meaning that it can be operated at lower gate-source voltages than traditional high-threshold MOSFETs. This makes it suitable for use in low-voltage circuits, such as those found in portable electronic devices. In addition, the IRL3803STRR has a very low on-resistance of 0.35 ohms and an off-state leakage current of only 0.1uA.

The IRL3803STRR operates in a simple dual-gate configuration. The two MOSFET transistors are connected in parallel with each other, with one transistor being the primary switch and the other being the secondary switch. When the primary switch is turned on, the secondary switch turns on as well, allowing current to flow. Conversely, when the primary switch is turned off, the secondary switch is also turned off, stopping the current flow.

The IRL3803STRR is typically used in applications that require high efficiency and low voltage operation, such as in AC/DC power converters, DC/DC converters, and switching regulators. Additionally, it can be used to switch between different voltage levels, making it suitable for use in DC motor speed control, load sharing, and other similar applications. The IRL3803STRR is also capable of operating at temperature ranges of -55°C to 150°C, making it suitable for use in extreme temperatures.

In conclusion, the IRL3803STRR offers excellent switching characteristics and low power loss, while operating at medium and high voltages. With its low gate-charge and on-resistance characteristics, it is ideal for switching applications that require efficient power control. In addition to its AC/DC and DC/DC converter applications, the IRL3803STRR can also be used in DC motor speed control, load sharing, and other similar applications. Furthermore, its operating temperature range of -55°C to 150°C makes it ideal for use in extreme temperature environments.
