Innovative Packaging for OptiMOS™ MOSFETs

SuperSO8/S3O8 – The Intelligent Way to Highest Efficiency and Power Density

SO8S308 Diagram

In applications like synchronous rectification in server and desktop, motor drives and DC/DC converters in telecom, high power density and high efficiency are the major driving factors. The trend set by Infineon to move from TO-220 to SuperSO8 in servers reduces the volume consumption drastically. With three times lower parasitics compared to TO-220, SuperSO8 offers the highest efficiency and lowest design efforts due to reduced spikes.


CanPAK™ – Best Thermal Behavior in a Tiny Footprint

CanPAK M and CanPAK S

CanPAK™ portfolio is the best fit for a broad number of industrial applications such as voltage regulator for servers, DC/DC converters in telecom, solar micro inverters and Maximum Power Point Trackers (MPPT), low voltage drives and synchronous rectification a in server and desktop. With only a 31mm2 footprint, CanPAK™ M allows 79% space reduction in power components on the board compared to traditional D2PAK. In addition, the metal 'Can' enables double-sided cooling along with almost no package parasitic inductances, leading to higher systems efficiency.


Power Stage 3 x 3 and Power Stage 5 x 6 – Save Space, Minimize Losses, Boost Efficiency

Power Stage 3x3

Dual FET power stages in a single leadless SMD package integrate the low- and high-side MOSFET of a synchronous DC/DC converter into a 3 x 3 mm2 or 5 x 6 mm2 package outline. Designers are able to shrink their designs up to 85% by replacing two separate discrete packages such as SO-8 or SuperSO8 with this new package.

Both the small outline and the interconnection of the two MOSFETs within the package minimize the loop inductance which boosts efficiency. With the new OptiMOS™ technology, power stage 3 x 3 and power stage 5 x 6 achieve a peak efficiency of 93.5%. Power stage 3 x 3 can handle an application current up to 12, 5 A and power stage 5 x 6 up to 30 A.
