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. We offer simple function optocouplers for low-bandwidth/general switching applications, high performance optocouplers for high bandwidth/high-gain applications, high-voltage optocouplers for AC load switching applications, and other complex functions that provide unique performance characteristics. In addition, we offer Infrared components, ranging from infrared light emitting diodes (LEDs), photodetectors, transmissive and reflective opto-sensors, and customized products to meet specific design requirements. All of our optoelectronics products are lead (Pb) free and RoHS compliant. In addition, they are certified by major safety regulatories.

Fairchild’s high performance optocouplers offer best-in-class common mode transient immunity resulting from our patented coplanar packaging technology, Optoplanar®. With their high speed data rates, these optocouplers are ideal for high speed data communications. Portable and compact electronic devices require optocouplers that reduce power consumption and save space. The 3.3V supply voltage specification reduces power consumption by 33%, while 5-pin Mini-Flat Package (MFP) and dual channel 8-pin SOP packaging optimize mounting density.

To meet the growing demands of today’s designs, Fairchild offers optocouplers capable of withstanding operating temperatures up to +125°C. The Microcoupler™ devices, designed in ball-grid array (BGA) package, are the only plastic package optocouplers capable of meeting this temperature limit enabling improved Current Transfer Ratio (CTR) stability at elevated temperatures. Our 4-Pin full pitch MFP and 4-Pin DIP, phototransistor output optocouplers are all rated with a maximum operation temperature of +110°C.
