What is the Diodes Founding Story?
The Diodes Company, originally established in 1959 as David Lloyd, began its journey as a regional semiconductor trading firm. For its initial three decades, the company operated with a modest presence, primarily serving businesses in the vicinity of its Westlake Village, California headquarters, with annual revenues not exceeding $10 million by the early 1990s.
The Founding Story of Diodes
The Diodes Company's origins trace back to 1959 when it was founded as David Lloyd, a regional semiconductor trading company. Its early years were characterized by a localized focus and modest financial performance, with revenues around $10 million by 1990.
- Established in 1959 as David Lloyd.
- Primarily a regional semiconductor trading company for its first three decades.
- Annual revenues were under $10 million in the early 1990s.
- The Diodes Company history saw a major shift in 1990.
A significant turning point in the Diodes Company history occurred in 1990 when Silitek Corporation, a Taiwanese semiconductor rectifier manufacturer, acquired a 46% stake, becoming the majority shareholder. This acquisition led to a strategic shift, with control eventually passing to Silitek's subsidiary, Lite-On Power Semiconductor Corporation. This event marked the beginning of an aggressive growth phase for Diodes, transforming its management and business philosophy from a trading model to a fully integrated manufacturing and distribution operation, a key aspect of its Growth Strategy of Diodes.
Transformation Through Acquisition
The acquisition by Silitek Corporation in 1990 was a pivotal moment for Diodes Incorporated, injecting new capital and strategic direction. This event propelled the company from its humble beginnings as a regional trader into a significant player in the semiconductor manufacturing industry.
- Silitek Corporation acquired a 46% stake in 1990.
- Lite-On Power Semiconductor Corporation gained control.
- Shifted from trading to integrated manufacturing and distribution.
- Focused on product line expansion and enhanced customer service.
While precise details regarding the initial founders of David Lloyd are not widely publicized, the 1990 acquisition by Silitek effectively redefined the company's trajectory. This strategic move laid the essential groundwork for Diodes Incorporated's subsequent expansion and success within the competitive semiconductor manufacturing sector, marking a critical chapter in its Diodes Incorporated timeline.
