PAST HISTORY (1991-2006):  Industrial Semiconductor was founded in 1991 by Fred Marquardt.  With an ever-present desire to manage his own company, Mr. Marquardt began his training in a radio/TV repair shop which then led to more formal training with the United States Air Force. After military service and with a background in a vacuum tube and solid-state electronics he was then selected to be part of the SCR development team at National Electronics where many new innovations in the manufacturing of SCRs were developed.

During his time at National, Mr. Marquardt was elected to serve on the JEDEC Industry Standards Committee in Washington DC where he assisted with developing the rating and testing standards for the Power Semiconductor industry.  In addition, he became the Application Engineering Manager which allowed him to work with many of the foremost power electronic design engineers of the day.  It was during this time that some of the early company developments began.

Several of the early company products, and which are no longer supported or made, included the first all solid state timing system for SCCA automobile racing.  The first solid-state scoreboard system installed at NASCAR automobile race tracks, and the first completely portable solid state timing system designed for the Ford Motor Company road racing team.

During the '80s Mr. Marquardt was employed as the first product manager at a fortune 500 company for their High Power Semiconductor products.  There he again was able to develop techniques and know how to provide the level of service and products the customers needed and deserved.

The Business excelled and in 2004 the our business became a Corporation. Industrial Semiconductor, Inc,  which is a Mainline Wholesale Distributer of of High Power Semiconductors made by the leadin world Manufacturers, such as Dynex, Times Electric, RIRI Power Electronics limited, GE, Westingting house, Infinion, Powerex, Mitsubishi, Westcode, And IXYS

2007 - Present:    In in 2007, Steven Malavolti, a 20 year veteran United States Navy Cheif Petty Officer,  was hired.   His military attention to detail and background in Elector Hydraulics enable hime to quickly grasps the power semiconductor field. First working as technician, Then ultimately working his way to General manager in 2010.  Outside fo the office, Steve became an Adjunct Faculty Instructor at the local Community College in electrical Wiring, AC/DC Theory, and Renewable Wind turbine Energy, which he still teaches part-time today with 16 years of dedication.  

In 2015 the company changed Owners to Steve Malavolti as the CEO,  which allowed Fred to slowly retire at his own pace.  Industrial Semiconductor, Inc business model is to distribute High Power Semiconductors such as SCRs, DIODES, BRIDGE MODULES, THYRISTOR MODULES, DIODE MODULES, GTOs.  

We are not a ecommerce site that advertises a number..
