Superjunction 500V CoolMOS Products for Consumer and Lighting Applications

Infineon Technologies introduced the 500V CoolMOS CE, a new series of CoolMOS products. When used to design power supplies in price sensitive applications such as consumer electronics, PC Silverboxes and Lighting SMPS (Switched-Mode Power Supply), the new devices represent an attractive alternative to standard MOSFETs. Infineon's 500V CoolMOS™ CE combines all benefits of modern Superjunction MOSFETs: low area specific on-state resistance, reduced switching losses and high body diode ruggedness.

Using Superjunction technology provides improved efficiency especially at light load conditions - thus, this new series of CoolMOS™ CE represents an energy-efficient and cost attractive alternative to standard MOSFETs. The low area specific on-state resistance (RDS(ON) × A) enables lower conduction losses, reduces energy stored in output capacitance (E oss) and minimizes switching losses. Lower gate charge (QG) improves light load efficiency while not compromising full load efficiency. This, combined with the outstanding quality and reliability of CoolMOS™ technology, provides lower system cost and a reduced cost of ownership. High body diode ruggedness and reduced reverse recovery charge (Q rr) make it the perfect solution for soft switching applications. The new devices are easy to design in and to use given their nicely controllable switching behavior. .

First samples of 500V CoolMOS™ CE in 280mOhm and 500mOhm Rds(on) in TO-220 package are available. By May 2012, first samples of 500V devices in 280mOhm, 500mOhm and 950mOhm Rds(on) in DPAK and TO-220 FullPAK packages will be available. First OEM ramp-ups are expected in May 2012. .

Engineering sample is US $1.12 per piece (IPP50R280CE; 500V, 280mOhm in TO-220).
