CKE

CKE was created in 1980 through the acquisition of the FMC Syntron metallic rectifier and surge suppressor product lines, as well as the General Electric, International Rectifier, Westinghouse and Sarkes-Tarzian (ST-Semicon) selenium lines. Later, CKE began to supply Metal Oxide Varistors (MOVs), providing direct replacements for most of the Harris, GE, Panasonic and Siemens MOV products. CKE introduced the TRANZAP line to provide replacements for silicon zener products similar to those made by General Semiconductor, Motorola and Semicon.In 1989, CKE acquired the high voltage channel stack line formerly owned by Westinghouse/Powerex, adding a high voltage breadth to its line of low to medium power silicon assemblies. In 1993, the International Rectifier lines were added, which included the popular half and full wave controlled SCR assemblies. Dean Technology Inc., HVCA's parent company acquired CKE in 1999, which expanded the product line and combined the strengths of the two engineering departments. Dean Technology Inc. purchased Electronics Manufacturing Inc. (EM) based in Mobile, Alabama in 2001. EM manufactured high voltage diode assemblies similar to those of HVCA and CKE, so production has been moved into those facilities. The former owner of EM joined the Dean Technology team further expanding their technology with his specialty - RF and transmitter design and repair.In 2002, Dean Technology Inc. purchased the silicon carbide varistor line made by Therm-0-Disc, a division of Emerson Electric, combining it with the CKE operation. As a result, CKE makes the industry's widest variety of suppression products and offers suppression capabilities that no other company can match.
