Working Principle

The APT45GP120B2DQ2G is an IGBT, which stands for insulated gate bipolar transistor. Like a MOSFET, they combine som properties of both bipolar transistors and MOSFETs, and they use isolating gate circuits to control the current between source and drain. Essentially, IGBTs are designed to act as a current switch, where the voltage to the gate controls the current flow among the source and drain.

The working principle of the APT45GP120B2DQ2G is that when a positive voltage is applied to the gate terminal, the controlling element between the source and the drain is activated, and current flows from the source to the drain. As the voltage increases, the current also increases, and conversely, as the voltage decreases, so does the current. In this way, the IGBT is able to control the current flow by controlling the voltage applied to the gate terminal. The APT45GP120B2DQ2G also has a collector-emitter breakdown voltage of 1200V and a collector-emitter saturation voltage of 2V, making it suitable for high current and high voltage applications.
