The DMG964H30R is a high-performance, high-power N-Channel MOSFET Array is a versatile device designed to improve efficiency, reduce losses and achieve high switching frequency operations in critical environments. It is best suited for applications such as DC/DC converters, motor control and off-line switching applications such as lighting and power supplies. It is also ideal for high current load switches and other high-speed power management applications.

The DMG964H30R is a pre-biased type MOSFET array that consists of four discrete N-Channel MOSFETs in a single surface mountable package. This device offers versatile protection and reliability in spite of its small package size. It is optimized to provide a wide range of operating current and has improved resistance to hot-spotting, leakage and surface noise.

The device offers an embedded circuit that combines pre-bias, overload and underload protection features and a built-in short circuit protection for better reliability. It also features a choice of two logic thresholds for improved compatibility between the logic threshold and the MOSFET.

The DMG964H30R is provided with a floating gate which is used to depress the threshold voltage, resulting in enhanced efficiency and improved switching performance. This floating gate also helps to ensure a low on-resistance and high speed turn-on and turn-off times, while providing a high corrosion resistance due to its hermetic sealed package.

The DMG964H30R features a temperature compensated pre-bias current source for improved reliability and thermal management. This pre-bias current source ensures that the device does not enter thermal runaway mode and helps to minimize thermal stress, reducing overall power dissipation. This pre-bias current source is also capable of protecting the device in case of faults in the gate circuit.

The DMG964H30R is also provided with a low gate-charge short circuit protection which reduces gate current and power dissipation. It further improves the reliability of the device by providing protection against overload and over-voltage. This low gate-charge protection reduces the risk of current hogging and helps to reduce EMI emissions.

The DMG964H30R is ideal for high-power applications, as it offers superior performance in terms of efficiency, thermal management and switching frequency. Its basic operating principle is based on gate voltage control and gate current control. Its floating gate is used to initiate the conduction process, while the pre-bias current source is used to keep the device in its active state, thereby providing superior power efficiency. Its embedded protection features and low gate-charge protection are designed to reduce power loss and extend the device\'s lifespan. It is also capable of operating at high-speed switching frequencies and is ideal for applications that require high speed switching and high current operations.
