Based on the TRENCHSTOP IGBT7, Infineon Technologies’ EconoDUAL 3 1200V module provides a leading nominal current of 900A, enabling a 30 percent higher inverter output current for the same frame size compared with legacy solutions. Based on micro-pattern trench technology, the TRENCHSTOP IGBT7 chip performs with much lower static losses compared to the IGBT4, with an on-state voltage is reduced by up to 30 percent for the same chip area. The power modules feature a maximum allowed overload junction temperature of 175°C.
Another improvement concerns the freewheeling diode, which has also been optimized for drive applications. The forward-voltage drop of the emitter-controlled 7th generation diode (EC7) is now 100 mV lower than the forward-voltage drop of the EC4 diode, with reduced oscillation tendency during diode turn-off. The higher power density of the EconoDUAL 3 helps to avoid paralleling of modules. The EconoDUAL 3 module comes with an improved PressFIT housing for handling higher currents and temperatures, and is available with pre-applied thermal interface material.
