IRG7PSH73K10PBF Application Field and Working Principle

IRG7PSH73K10PBF is a high power insulated gate bipolar transistor (IGBT), which is mainly used in the field of power electronics. An IGBT is a combination of a bipolar junction transistor (BJT) and an MOSFET, which is based on the principle of a metal-oxide field-effect transistor (MOSFET). It is constructed similarly to a power MOSFET, but it has an additional gate control. This gate control allows the current to be managed more efficiently, resulting in greater power density. In addition to its higher power efficiency, it also has several advantages over other power semiconductors, such as higher current-carrying capacity, lower drive power requirements, and lower thermal impedance.

Working Principle of an IGBT

An IGBT combines the advantages of the bipolar junction transistor (BJT) and the metal-oxide field-effect transistor (MOSFET). It is designed to be used in applications where high power density and fast switching is needed, such as motor drives and power conversion. The IRG7PSH73K10PBF has an open-base NPN bipolar junction transistor (BJT) at the drain side instead of the regular closed-base NPN BJT. The gate is powered by a DC voltage, and the base voltage is controlled by a high-speed switching circuit.

When a small current passes through the gate terminal, a small amount of charge is stored on the gate, which causes it to become conductive. This in turn causes the BJT to become conductive, and it allows current to flow from the drain to the source. As the gate voltage is increased, the junction of the transistor becomes increasingly conductive. This increases the amount of current that can flow through the device and makes the transistor more efficient.

When the gate voltage is reduced, the junction becomes less conductive, and the current is reduced. As the gate voltage continues to decrease, the junction eventually reaches a low conductivity state and no current can flow through the device. This is called reverse blocking and is the normal operating regime of the IGBT device.
