Freewheeling diodes are one of the major components for modern IGBT modules and have to satisfy a number of demands. Especially in hard switching applications, such as inverters for industrial drives or UPS, a soft switching behavior of the diode is - besides low losses and high ruggedness - of major interest. A high softness reduces EMI problems and enables a faster turn-on of the IGBT. In this work,...
In this paper we present a novel 3.3 kV diode concept with anode side buried p doped layers. These p doped layers could retard the arising of the electric field and consequently postpone the onset of the dynamic avalanche at the pn-junction. Isothermal numerical simulation results suggested that this novel structure could permit balanced improvement of the static as well as the dynamic behaviors.
In this paper, we present a novel 3.3kV diode structure with controlled injection of backside holes, i.e. CIBH diode. This new diode structure features buried floating p layers at the cathode side. These p doped areas prevent the formation of high electric field strength at the nn+ junction and accordingly avoid the avalanche generation at the nn+ junction. The CIBH diode concept provides, compared...
