The IPN50R3K0CEATMA1 is a single field-effect transistor (FET) from Infineon Technologies which belongs to their OptiMOS™ low-voltage transistor range. The FET has a rated maximum voltage of 30 V, a drain current rating of 4 A, and total gate charge of 11 nC, making it suitable for a wide variety of applications. This guide will discuss the main features of the IPN50R3K0CEATMA1, its application fields and working principle.

Features

The IPN50R3K0CEATMA1 has a number of key features which make it suitable for a range of power switching applications. These include its relatively low on-resistance of just 0.3 Ω, meaning that it can pass higher currents with lower losses than many similar FETs; its relatively low gate charge of just 11 nC, which allows the FET to switch on and off faster; its 30 V maximum voltage rating, allowing it to be used in many automotive and industrial applications; and its low threshold voltage, which can reduce power losses in switching applications.

Applications

The above features and the low on-resistance of the IPN50R3K0CEATMA1 make it suitable for a variety of power switching applications, including those in automotive and industrial systems. In automotive applications, it can be used for DC motor driving, power management, and start-stop systems, while in industrial systems, it can be used to control the current flow in power supplies and motor control systems. The FETs low on-resistance also makes it suitable for use in power converters and battery chargers, where reduced power losses are desired.

Working Principle

The IPN50R3K0CEATMA1 is an N-channel enhancement-mode FET, which means that it operates by allowing a current to flow along a conducting channel when an appropriate positive voltage is applied to its gate terminal. The resistance of the channel is controlled by the voltage applied to the gate terminal, and can be varied from a high resistance (when the voltage is low) to a very low resistance (when the voltage is high). This can be used to switch the FET on and off, thereby controlling the flow of current in the circuit.

When the FET is switched on, the source terminal will be connected to the drain terminal, allowing current to flow through the FET. As the current passes through the FET, it will generate a voltage drop across its terminals as a result of the resistance of the channel. This voltage should ideally be equal to the voltage applied to the gate terminal, as this ensures that the current is flowing through the FET at its maximum efficiency.

The total amount of current that can pass through the FET is limited by its maximum current rating. This is determined by the size of the conducting channel, as if too much current is applied, the FET can overheat and be damaged. To ensure that the FET does not overheat, it is important to ensure that the maximum current rating of the FET is not exceeded.

The IPN50R3K0CEATMA is a versatile FET which can be used in a variety of power switching applications. With its low on-resistance, low gate charge, and high voltage rating, it can be used to control the current flow in automotive, industrial, and other systems. By understanding its operating principles and features, it is possible to select the most suitable FET for any given application.
