Infineon Technologies has introduced the 500V CoolMOSTM CE, a new series of CoolMOSTM 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 are an alternative to standard MOSFETs.

Infineon’s 500V CoolMOSTM CE combines the benefits of modern Superjunction MOSFETs: low area specific on-state resistance, reduced switching losses and high body diode ruggedness.

“The new 500V portfolio enables our customers to reach higher energy efficiency levels while at the same time offering a very attractive price-performance ratio, which makes this new set of CoolMOSTM CE devices an excellent alternative to standard MOSFETs in targeted applications,” said Jan-Willem Reynaerts, Product Segment Head of High Voltage Power Conversion at Infineon Technologies.

Using Superjunction technology provides improved efficiency especially at light load conditions – thus, this new series of CoolMOSTM 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 (Eoss) 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 CoolMOSTM technology, provides lower system cost and a reduced cost of ownership. High body diode ruggedness and reduced reverse recovery charge (Qrr) make it a solution for soft switching applications. The new devices are easy to design in and to use given their nicely controllable switching behavior.

500mOhm Rds(on) in TO-220 package are available and by next month, 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.
