HV Component Associates (HVCA) is a specialized semiconductor company with roots dating back to the early 1960s, when it operated as the rectifier division of Galileo Electro-Optic Corporation. The division later became an independent entity, and in 1989 it acquired Conditioning Semiconductor Devices Corporation (CSdc), gaining expertise in epoxy power blocks formerly produced by International Rectifier Corporation. HVCA focuses on the design, development, and manufacture of high-voltage rectifiers, bridge rectifiers, and custom engineered assemblies. Its primary product lines include high-voltage silicon rectifiers, fast recovery rectifiers, and high-voltage stacks. Through its association with CKE, the company also offers metal oxide varistors (MOVs), selenium suppressors, silicon carbide varistors, and high-voltage disk ceramic capacitors. HVCA excels in providing tailored solutions for demanding applications such as power supplies, X-ray equipment, induction heating, and electrostatic precipitators. Manufacturing capabilities span standard products and full custom assemblies, often integrating multiple passive and active components. With over five decades of experience, HVCA has built a reputation as a reliable supplier to industrial, medical, and military sectors. Its engineering team supports customers from prototype to production, ensuring high reliability and performance. Although not a volume giant in the broad semiconductor market, HVCA holds a niche leadership position in high-voltage discrete components and assemblies.
