Copack IGBT and diode in ISO247 package

The ITF48IF1200HR is a new ISO247-packaged copack IGBT and diode featuring the lowest thermal resistance, lowest weight and high voltage isolated backside. The new package enables higher current and power ratings when compared to other isolated package technologies. 

The new ISO247 package is a direct replacement for the TO247 package as it has the same dimensions and a mounting hole like the TO247. With a 3kV internal insulation to the heatsink, the new ISO247 is therefore simpler to isolate and mount. The ISO247 is a new member of the ISOPLUS family, which offers isolated package versions of industry standard packages such as TO247 and TO264 with the same footprint. Compared to the ISOPLUS247 series, the ISO247 gives the user a further improvement in thermal resistance, which can be used for either higher output current or improved reliability at the same power level. A patented package construction allows the usage of the ISO247 package without using thermal grease, and offers a lower junction to heatsink thermal resistance than the standard isolation of a TO247 with a thermal pad. 

ITF48IF1200HR is a copack of a fast 1200V Trench IGBT and soft recovery SONIC diode at a rated IGBT current of 48A at a case temperature of 100 degrees C. Turn off energy per pulse is 2.4 millijoules when turning off a current of 40A at a bus voltage of 600V and a junction temperature of 150 degrees C. Further features are a maximum junction temperature of 175 degrees C and a short circuit capability of 10 microseconds.
