The world's largest supply platform for sources of shortages and hard-to-find parts
Supplier Introduction

Fairchild Semiconductor International, Inc. was an American semiconductor company based in San Jose, California. 

Founded in 1957 as a division of Fairchild Camera and Instrument, it became a pioneer in the manufacturing of transistors and of integrated circuits.

Schlumberger bought the firm in 1979 and sold it to National Semiconductor in 1987; Fairchild was spun off as an independent company again in 1997.

On September 2016, Fairchild was acquired by ON Semiconductor.

In the previous Fairchild Semiconductor was a leading global supplier of power analog, power discrete, and optoelectronic components that optimize system power. 

Recognized as The Power Franchise?, Fairchild Semiconductor offers the industry's broadest portfolio of components for today's leading electronic applications in the computing, communications, consumer, industrial, and automotive segments.

Fairchild Semiconductor is a leading global provider of semiconductor technology that powers the products and makes them more energy efficient. 

Fairchild continues to build on its rich history of innovation to address one of the greatest challenges-reducing wasted energy and improving efficiency in an increasingly power-hungry world. 

It has also been selected as one of China's leading suppliers in the highly competitive discrete semiconductor category at China Market Electronics Component Manufacturer Awards(CMECMA).

Besides, it was awarded "The 8th Best Foreign Corporation Award" and was ranked top out of the 173 foreign manufacturing companies. 

Fairchild Semiconductor is a leader in the design and production of optoelectronics products, offering a broad range of package platforms, incorporating various combinations of input and output configurations. 

It has products including simple function optocouplers, high performance optocouplers, high-voltage optocouplers. 

In addition, it offers infrared components, photodetectors, transmissive and reflective opto-sensors, and customized products to meet specific design requirements. 

Fairchild is The Power Franchise?, providing leading-edge silicon and packaging technologies, manufacturing strength and system expertise for consumer, communications, industrial, portable, computing and automotive systems.

It will continue to work closely with leading electronic manufacturers to understand the power challenges of new platforms and develop innovation technologies that break new barriers in efficiency.


In April 2011, Fairchild Semiconductor acquired TranSiC, a silicon carbide power transistor company, originally based in Sweden.

On November 18, 2015 ON Semiconductor made an offer to acquire Fairchild Semiconductor for $2.4 billion, or $20 per share after a few months of speculation that Fairchild was seeking a potential buyer.

On April 10, 2016 Fairchild Semiconductor moved its headquarters from San Jose (3030 Orchard Pkwy) to Sunnyvale (1272 Borregas Ave.)

On September 19, 2016 ON Semiconductor and Fairchild Semiconductor jointly announced that ON Semiconductor has completed its announced $2.4 billion cash acquisition of Fairchild.

In the fall of 2016 the Fairchild 'ON' Semiconductor International closed the West Jordan, Utah manufacturing plant.
