    Abstract

    Dynamic Avalanche (DA) phenomenon poses a fundamental limit on the operating current density, turn-off power loss as well as reliability of MOS-bipolar devices. Overcoming this phenomenon is essential to ensure their safe operation in emerging electric transport. In this work, detailed analysis of 1.2 kV trench gated IGBTs are undertaken through experiments and calibrated TCAD simulations to show the fundamental cause of the DA as well as a method to achieve DA free design for ultra-high current density operation and reliability in 1.2 kV Si-IGBTs.
