Infineon offers medium voltage MOSFETs in CanPAK packaging

March 07, 2011 // By Paul Buckley
At APEC 2011, Infineon Technologies has revealed that medium voltage power MOSFETs, OptiMOS, are now available in the CanPAK package which uses DirectFET technology licensed from International Rectifier Corporation. The new devices can be used in a wide range of industrial applications like DC-DC converters, solar micro inverters, Maximum Power Point Trackers (MPPT) in solar energy systems, low voltage drives and synchronous rectification for servers.

The addition of 60 V-150 V MOSFETs to the Infineon CanPAK portfolio enables power system engineers to optimize designs for power density, efficiency and excellent thermal behavior while requiring minimum board space. This optimization contributes to cost savings and long operating life in applications ranging from servers to renewable energy systems.

Compared to standard discrete packages, the CanPAK metal ‘can’ construction enables double-sided cooling along with almost no package parasitic inductances, leading to highest efficiency and system miniaturization. Thermal resistance on the top side of the package is very low (1.5  K/W (Kelvin per Watt) vs. 55 K/W for a traditional DPAK), which allows efficient device cooling from still air convection in the power conversion systems of solar energy installations or fan-assisted airflow, which is common in servers for data centers.

The advantages of CanPAK are complemented by the performance of OptiMOS MOSFETs, which feature industry’s lowest R DS(on), and Q g across the entire voltage range. Low Gate charge (Q g), results in the lowest switching losses in fast switching applications, like isolated DC-DC converters for telecom applications as well as solar micro inverters and MPP Trackers in solar energy systems.

Claiming the industry’s best R DS(on), Infineon’s CanPAK products exhibit lowest power losses in high current applications such as motor control. They are also ideally suited for industrial applications like synchronous rectification in Switched Mode Power Supplies (SMPS).

Availability and Pricing

Engineering samples are available now, production release is in April 2011. OptiMOS 60 V-150 V in CanPAK comes in R DS(on) classes from 2.8 to 28 mOhm. For small quantities (10k units), pricing begins at $0.40.
