The Insulated Gate Bipolar Transistor (IGBT) is a pivotal power semiconductor device in the field of power electronics, combining the high-current handling capability of the Giant Transistor (GTR) with the high-speed switching characteristics of the Power MOSFET. It boasts high input impedance, low on-state voltage drop, and excellent thermal stability. IGBTs have found widespread applications in electric vehicles, industrial automation, power transmission and distribution systems, and more. This article delves into the key specifications and characteristics of a specific IGBT model, the FGY75N60SMD.

1. Basic Principles and Structure of IGBT

The IGBT is a three-terminal device comprising a Gate (G), Collector (C), and Emitter (E). Its internal structure is intricate, merging the features of both a MOSFET and a Bipolar Junction Transistor (BJT). The Gate of the IGBT is controlled by the MOSFET section, featuring high input impedance and low drive power. Meanwhile, the Collector and Emitter are composed of the BJT section, providing high-current handling capability and fast switching speeds.

When a positive voltage is applied to the Gate of the IGBT, the MOSFET section forms a conductive channel, allowing the drain current to flow. Simultaneously, the BJT section controls the amplification of the drain current, resulting in a high overall current gain. When a negative voltage is applied to the Gate, the conductive channel closes, reducing the drain current and achieving device turn-off.
