Book excerpt: The Insulated Gate Bipolar Transistor (IGBT) is a power semiconductor device widely used in high-speed switching applications. Due to aging and internal heating, the device is prone to a failure mechanism known as latch-up in which, changes in the threshold voltage and the on-state voltage of the device may ultimately lead to loss of switching control. Since IGBTs are typically operated at high voltages and currents, the datasheets do not provide information on the static characteristics of the device for voltages close to the threshold, which is a useful region for understanding the underlying device physics. In this thesis a simplified IGBT model is presented that attempts to provide a magnified view of the static characteristics close to the threshold voltage. The model is developed based on the device structure and is optimized to fit the measured characteristics in the near-threshold voltage range.
