IRLR8503TRLPBF

The IRLR8503TRLPBF is a high-performance and cost-effective MOSFET manufactured using eZERO™ technology, which offers excellent thermal characteristics and low on-state resistance. This FET has been designed for high-power and high-frequency switching applications and is ideal for use in a range of motor control, audio and power systems.

The IRLR8503TRLPBF consists of an enhancement MOSFET in a single package, making it suitable for use in a variety of applications. It has a drain source voltage of 500V, a maximum continuous drain current of 15A, a maximum drain source on-state resistance of 0.08 ohm, and a maximum gate source voltage of +/- 20V.

The IRLR8503TRLPBF is commonly used in power applications such as power supplies and solar inverters, for motor control applications such as servo motors and variable-speed drives, and for audio applications such as audio amplifiers. The FET has a relatively low gate charge, making it suitable for high-speed switching applications. Additionally, the FET’s low on-state resistance, or RDS(on), offers high efficiency and reduced power losses.

The working principle of an MOSFET is based on the “four-terminal network” theory. The theory states that when a voltage is applied to the gate terminal of an MOSFET, it creates an electric field across the entire device. This electric field alters the behavior of the junction, allowing the current to flow from the source to the drain. The current flowing through the drain is regulated by the voltage applied to the gate terminal. By adjusting either the voltage or the gate resistance, the current can be reduced or increased.

Additionally, when two or more FETs are connected together, they form what is known as a “MOSFET combination element”, or “MCD”. When a voltage is applied to the drain, the FETs’ internal resistance rises, thus limiting the current that flows through the element. This is commonly used in switching applications such as drivers, amplifiers and motor control applications.

In conclusion, the IRLR8503TRLPBF is a high-performance and cost-effective MOSFET designed for high-power and high-frequency switching applications. Its low gate charge and low RDS(on) make it suitable for a range of power, audio and motor control applications. Additionally, its four-terminal network principle and ability to form MCDs provides high efficiency and power control.
