Single IGBTs are one of the most widely used power electronic devices in the world today. With their ability to switch high current with good efficiency and precision, they are an integral part in a variety of systems including industrial drives, motor control, medical instrumentation, and renewable energy applications. STGP10NB60SD is one such single IGBT, whose application fields and working principle are discussed in this article.

The STGP10NB60SD is a Field Stop IGBT rated at 10A, 800 Volt. Its low on-state voltage drop is suitable for high switching frequency applications, making it ideal for AC motor control, Uninterrupted Power Supply, vehicle charging and other high frequency applications. It also offers excellent EMI performance and has low thermal awareness.

The STGP10NB60SD also has reverse blocking voltage of 600V and a minimum breakdown voltage of 800V. This makes it suitable for applications that require protection against overload or short-circuit faults. The device has a low gate threshold voltage of 1.5V and a short turn-off time of 10µs, making it ideal for fast switching applications.

The working principle of an IGBT is based on the principle of PN junction which acts as a switch. IGBTs use two PN junctions connected in series, where the middle junction is controlled by a gate voltage. During operation, the gate voltage increases, reducing the voltage across the middle junction, thus allowing current to flow. Conversely, when the gate voltage is low, the voltage across the middle junction increases, blocking current flow.

The STGP10NB60SD IGBT is designed to provide operation at higher switching frequency and higher efficiency. It utilizes an advanced Shield Gate structure which allows the device to handle larger dI/dt, resulting in higher switching performance. The device also offers an optimized package structure which minimizes diode leakage current and optimizes heat distribution.

In summary, the STGP10NB60SD single IGBT has a wide variety of applications such as motor control, Uninterrupted Power Supply, vehicle charging and other high frequency applications, due to its low voltage drop and fast switching capability. Its advanced Shield Gate structure enables high switching frequency, while its optimized package structure minimizes diode leakage current and optimizes heat distribution. Finally, its two PN junctions connected in series enable the IGBT to act as a switch, controlled by a gate voltage.
