Transistor Devices Inc.
Cedar Knolls, New Jersey

The Company is a leading designer and manufacturer of high-power, fault-tolerant, uninterruptible electronic power supplies and other power systems used in mission critical applications.

Founded: 1951

The Company, founded in 1951, was primarily a supplier to the defense industry through the early 1990s. For fiscal 1998, substantially all of the Company's $116 million net sales were to non-defense related, OEM customers.
During the  years the Company expanded its operating capabilities in the United States and initiated manufacturing overseas. During this period, the Company more than doubled the square footage of its plants in the United States by opening new regional facilities including facilities located in Hackettstown, New Jersey; Hopkinton, Massachusetts; and San Clemente, California, which facilitated the growth in net sales during this period.  In addition, the Company established TDI Europe in fiscal 1997 and TDI China in fiscal 1998 thereby expanding its international operations.

This manufacturer was suggested by Antonio Marra.
