EL SEGUNDO, CA. November 1997 - International Rectifier (IR) announces the Super-247 package, offering the same power handling capability as the larger JEDEC TO-264 package and twice that of the common TO-247 but with a reduction in cost and footprint. The Super-247 offers power handling capability of 30 kW for Switch Mode Power Supplies (SMPS) and 10 kVa for Uninterruptible Power Supplies (UPS), with a maximum lead current carrying capability of 90 A, while the older packages are restricted to 70 A.

IR's state-of-the-art IGBT Silicon is being used in the Super-247, allowing it to handle comparatively more power than competitors' devices. As an example, the new 600 V IRG4PSC71UD is rated at an industry-high 100 A at 25°C and 50 A at 100°C. Vce(on) is 1.9 V max, complemented by the lowest switching losses available at this power level (0.68 mJ/A from a 360 V bus, or 0.9 mJ/A from a 480 V bus -- both including diode losses). IR's popular HEXFRED® ultrafast freewheeling rectifiers contribute greatly to the efficiency of the IGBT.

The Super-247 has the same outline as the industry-standard TO-247 (except that it is designed for clip-mounting, so it has no mounting hole); it can replace approximately two or more TO-247 FETs or IGBTs or even one or two of the much larger TO-264 package.

Initially, IR is offering a number of HEXFETs, IGBTs and IGBT/HEXFRED CoPacks in the new Super-247 package, with future plans for more part numbers and different devices. In continuing with IR's commitment to provide packages for specific end applications, their Super-247 is designed for use for mid-to-high power, off-line Switch Power Supply (SMPS), motor drive, Uninterruptible Power Supply (UPS) and welding applications.

Samples of the first devices will be available in January, 1998, with production runs starting in June 1998.
