Corporate History

  • Incorporated in 1979 as a privately held sales and marketing company specializing in Power Semiconductors  (rectifier, diodes, Thyristor, scr) and Electronic Components.
  • Initially, the company marketed and sold Selenium Rectifier products. An agreement was completed with Secowest of Torino, Italy a manufacturer of Silicon Power Semiconductors, to market their products in the United States.
  • In 1985 an agreement with Ansaldo / Poseico was reached for specialized power semiconductors.
  • International Rectifier acquired Secowest in 1987 and C&H Technology partnered with International Rectifier promoting power products.
  • In 1997 with the idea of advancement toward the future, C&H Technology increased engineering and manufacturing capabilities to include Power Assemblies, Power Hybrids, Clamps and Heat Sinks (Extruded and Bonded Fin).
  • Vishay acquired International Rectifier High Power Products in 2007 and C&H Technology has increased partnership with Vishay for power semiconductors, power capacitors, power resistors and Thermistors.
