new 1 mm-high surface-mount package houses the industry-standard TO-220 die size within a leadless outline measuring only 8x8 mm and features an exposed metal drain pad for efficient removal of internally generated heat. Its low profile will enable designers to achieve slimmer power supply enclosures enabling compact and stylish new products for today’s markets. This new standard is available from two companies: Infineon and ST will introduce MOSFETs using this innovative package, which is named ThinPAK 8x8 by Infineon and PowerFLAT™ 8x8 HV by ST, therefore providing customers with a high-quality alternative source.
“This type of package sets a new market standard for leadless SMD packages for HV MOSFETs, and is being introduced today in co-operation with STMicroelectronics,” said Jan-Willem Reynaerts, Product Line Manager HVMOS Power Discretes at Infineon Technologies. ”Silicon technologies like CoolMOS™ have reached such an advanced stage of fast and efficient switching, that the standard traditional through-hole packages more and more have become the limiting factor in getting to the next level of energy efficiency and power density.”
The ThinPAK 8x8 package is characterized by a very low source inductance of only 2nH (vs. 6nH for the D2PAK), a separate driver source connection for clean gate signals, as well as a thermal performance similar to the D2PAK. As a result, the ThinPAK 8x8 package enables faster and thus more efficient switching of Power MOSFETs and is also easier to handle in terms of switching behavior and EMI.
Infineon will initially offer three 600V CoolMOS™ devices in the new package: 199 mOhm (IPL60R199CP), 299 mOhm (IPL60R299CP) and 385 mOhm (IPL60R385CP).
