Infineon unveils 1 milli-ohms 40V power MOSFET in SuperSO8 package

Infineon Technologies AG has introduced the new OptiMOS 40V and 60V power MOSFET families optimized for synchronous rectification in Switched Mode Power Supplies (SMPS) such as those deployed in servers and desktop PCs. Other suggested applications include industrial applications such as motor control, solar micro inverter and fast switching DC/DC converter.

"Infineon is the first semiconductor company to introduce a 1milli ohms 40V MOSFET in a SuperSO8 package. This cuts the number of MOSFETs in the synchronous rectification of a 1,000W server power supply by half. Paralleling is no longer required and power density is increased dramatically," said Richard Kuncic, Senior Director Low Voltage Power Conversion at Infineon Technologies.

Infineon suggests by using the BSC016N06NS device from Infineon's new 60V family, in a SuperSO8 package that measures 5mm x 6mm, a 1.5% higher efficiency can be achieved at a 20% load condition in a solar micro inverter.

Infineon claims implemented on Infineon's advanced thin wafer technology, the new OptiMOS 40V and 60V families offer 35 percent lower R DS(on) and lower gate charge (Q g) reducing the Figure of Merit (R DS(on) x Q g) by 45 percent when compared to alternative devices. This allows power loss reduction of ten percent when the devices are used in the secondary side rectification of a server power supply.

A monolithically integrated Schottky-like diode in the 1milli ohms and 1.4milli ohms 40V SuperSO8 devices reduces the reverse recovery charge (Q rr) in synchronous rectification applications.

Availability and Pricing: The new OptiMOS 40V devices in SuperSO8 and S3O8 (3mmx3mm) packages are available in R DS(on) ranges from 1.0milli ohms to 2.3milli ohms and are priced at $0.50 USD and $1.05 USD per piece (10k pieces quantity).
The new OptiMOS 60V devices in SuperSO8 packages are available in R DS(on) classes of 1.6milli ohms and 2.8milli ohms and are priced at US $0.85 and $0.65. Additional devices are available in TO-220, S3O8, I²PAK (TO-262), D²PAK and DPAK (TO-252) packages with pricing from $0.54 USD for 6.0milli ohms R DS(on) to $1.5 USD for 1.0milli ohms R DS(on) ratings for 10k pieces quantity.
