The AUIRF7316QTR is an array of advanced low gate charge and ultra-low on-resistance (R_DS(ON) ) trench Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) designed and developed specially for switching applications. Arrays of this type are typically used for high-frequency, high-current, and low-power dissipation applications, due to their low gate charge and ultra-low on-resistance.

This device has single-gate, N-channel MOSFETs, and each MOSFET can be independently controlled via a Controlled-Axis (C-Axis) gate, which allows for the efficient interconnection of multiple transistors. The C-Axis gate is specially designed to reduce the resistance and capacitance of the gate-channel junction, resulting in reduced power dissipation and improved transient characteristics.

Other features of the device include an improved layout architecture that minimizes the parasitic effects of inductance and capacitance for higher efficiency operation, and improved thermal performance for up to 14A operation, allowing for operation at higher frequencies and higher current densities. Additionally, the device is insulated from the magnetic fields associated with switching applications, providing improved reliability and robustness.

The AUIRF7316QTR is primarily employed in a wide range of switching applications such as switching AC and DC loads, power converters, and motor drives. Since the device has an ultra-low on-resistance, it can reduce power losses in switching operations and helps to improve efficiency, thus saving energy. Additionally, the device is highly suitable for high-frequency applications due to its fast switching speed and low gate charge.

The working principle of the AUIRF7316QTR is based on the basic FET principles. Each transistor contains an insulated gate region separated from the channel by a reverse biased MOS gate-drain junction, where the gate is insulated from the channel by a gate oxide layer. The gate voltage controls the charge carriers in the channel, allowing or inhibiting the flow of current between the source and the drain. When the gate voltage is applied, a depletion region is created which allows for the controlled refinement of the on resistance of the transistor and provides an efficient means for controlling the on/off ratio at each gate.

In addition, this device provides an innovative C-Axis gate architecture, which provides improved control and reduced power dissipation compared to standard gate designs. This architecture is essential in switching applications where fast switching action is needed and higher-power dissipation is undesirable. By using this architecture, the device has improved switching efficiency and excellent transient characteristics.

The AUIRF7316QTR represents an advanced array of trench MOSFETs, which is designed to provide high current density, excellent power dissipation, and fast switching speed over a wide range of conditions. With its low gate charge, ultra-low on-resistance, and improved control architecture, this device is ideal for applications that require high current density, low power dissipation, and fast switching speeds.
