A Long and Intriguing History
In 2014 TF Semiconductor Solutions became an Independent solutions company spinning-off from TSI Semiconductors (formerly known as Telefunken Semiconductors America).  TELEFUNKEN has been a premier nameplate and innovator in all fields of electronics from radios to microprocessors to computer systems for over a century.

HEILBRONNFounded in 1903 in Berlin, Germany the company has always been on the forefront of new technologies. Some of the greatest geniuses of 20th century electronics have been associated with TELEFUNKEN. Nikola Tesla assisted TELEFUNKEN in constructing the first wireless transmission system between North America and Europe in 1911. Walter Bruch developed the PAL color television technology standard for the company in 1963.

TELEFUNKEN established its Heilbronn, Germany semiconductor facility in 1959. The TR 4 and TR 440 computers were initially developed by TELEFUNKEN in the late 1960's and were in use by many computing centers into the mid 1980's. 

ROSEVILLE FACILITYIn 2012 TELEFUNKEN acquired the 200mm (8”) manufacturing facility from Renesas Electronics expanding its reach into the Analog Mix-Signal and Automotive Markets.  Today, TF Semiconductor Solutions partners with TELEFUNKEN Semiconductor GmbH & Co KG in Germany and TSI Semiconductors, Inc. in Roseville, California.  Together we are continuing to extend this rich heritage into the 21st century in the rapidly expanding Power Management semiconductor market.
