Infineon Technologies has enhanced its 1200 V EconoDUAL 3 portfolio with the TRENCHSTOP IGBT7 chip by offering new current ratings from 300 A to 900 A. The broad range of current offers inverter designers a high degree of flexibility along with increased power density and performance. Featuring new current ratings, these new devices are suitable to be used in solar, drive applications, commercial, construction and agricultural vehicles (CAV), and for uninterruptible power supply (UPS) inverters.
Based on the new micro-pattern trench technology, the EconoDUAL 3 portfolio with the TRENCHSTOP IGBT7 chip feature a maximum overload junction temperature of 175°C.leads to lower static losses compared to the modules with an IGBT4 chipset. Moreover, its on-state voltage is reduced by up to 30 % for the same chip area. Not only this, the oscillation behavior and the controllability of the IGBT too have been improved. With the extended 750 A and 900 A versions, the EconoDUAL 3 package addresses an improved inverter power range. In addition, the PressFIT housing enables a fast and cost-efficient assembly.
The chip dimensions are tailored to enable optimization of the module layout for reduction in switching losses. This leads in a simplified design-in for applications with higher switching frequency. The 1200 V TRENCHSTOP IGBT7 EconoDUAL 3 portfolio is available from company website and its variants with pre-applied TIM will be made available soon.
