Toshiba Debuts Compact Package MOSFETs for Controlling Power Sources, Data Signals in Mobile Devices

October 8, 2015

IRVINE, Calif., -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced the launch of two new compact MOSFETs - the SSM3K35CTC and SSM3J35CTC. Housed in a newly developed compact package (CST3C) the SSM3K35CTC and SSM3J35CTC are suitable for controlling power sources or data signals in mobile devices such as smart phones and wearables.

When it comes to the overall footprint, Toshiba’s CST3C package exceeds industry standards. In fact, the CST3C package is just one-third the size of the industry standard SOT-723 package. This makes Toshiba’s new MOSFETs suitable for high density mounting, and gives them the ability to achieve lower on-resistance when compared with products with a standard SOT-723 package.
