Introduction

The DPG60IM400QB (DPG60IM400QB) is a single rectifier from Diodes Incorporated. It is primarily applied in high-current power switch Mode Power Supplies (SMPSs), low-voltage DC-DC Converters, and UPSs. This high-performance part also offers a high level of integration, with low parts count and a high power density.

Applications

The DPG60IM400QB is specially designed for demanding applications in the power electronics industry. It is well suited for high-current power switch Mode Power Supplies (SMPSs), low-voltage DC-DC Converters and Uninterruptible Power Supplies (UPSs). It has a wide operational input range and can operate from either a permanent or alternating current source. It is particularly useful in solar and automotive applications, as it provides high efficiency with low power loss and can handle high-frequencies.In addition to these applications, the DPG60IM400QB can also be used in other high power applications such as flyback, forward and resonant conversion (including LLC) topologies. The device has a variety of features which makes it suitable for these applications, such as its wide input voltage range, low junction capacitance, low gate charge and fast switching.

Features

The DPG60IM400QB single rectifier features a high current rating, low energy losses and excellent surge capability. It has a surge rating of 150A, a reverse voltage of 400V and a forward voltage of 0.6V. It is capable of providing high current output at low on-state voltages, making it a good choice for high-power switching applications. It also has a low gate to source capacitance, with a value of 25pF. This can reduce switching losses and minimize EMI interference.The device also has an internal diode for the reverse current, which eliminates the need for an external diode and can save space on the board. The DPG60IM400QB is also capable of handling up to 2K Hz switching frequencies, meaning it can be incorporated into a wide range of different applications.

Working Principle

The DPG60IM400QB single rectifier is an insulated-gate bipolar transistor (IGBT) with a built-in diode. An IGBT is a voltage-driven device, meaning that the current between its source and drain is controlled by the voltage that is applied to its gate. An IGBT consists of four p-n junctions, one of which is the diode in this case.The IGBT works by controlling the on-state resistance of the diode depending on the gate voltage applied to it. When the gate voltage is higher than the threshold voltage (Vth), the drain-source voltage drops, and a conducting path is formed. This allows current to flow from the drain to the source and vice versa, thereby allowing a high-current output. When the gate voltage is below Vth, the resistance of the device is raised, which stops the flow of current. The DPG60IM400QB can be used in both switching and linear applications, depending upon the gate voltage applied to it. When used in a switching application, the IGBT switches on and off quickly, with low EMI and power losses. When used in a linear application, such as a low-voltage DC-DC converter, the IGBT will regulate the current flow depending on the gate voltage, allowing for more precise control of the output.

Conclusion

The DPG60IM400QB single rectifier from Diodes Incorporated is a high-performance part that offers a high level of integration, with low parts count and a high power density. It is specifically designed for demanding applications in the power electronics industry, such as high-current power switch Mode Power Supplies (SMPSs), low-voltage DC-DC Converters and Uninterruptible Power Supplies (UPSs) and can also be used in solar and automotive applications. The device has a wide operational input range, low gate to source capacitance and low on-state voltages, meaning it can be incorporated into a wide range of different applications with minimal losses and EMI.
