Reliable Optoelectronic Devices & Optocouplers for Industry Communication

Fairchild Semiconductor is a leader in the design and production of optoelectronics devices. We offer optocouplers for low bandwidth/general switching applications, high performance optocouplers for high bandwith/high-gain applications, high-voltage optocouplers, infrared components, and other customized products that provide unique characteristics.

Our broad range of optoelectronic & optocoupler devices combine numerous input and output configurations to reduce power consumption and provide superior noise immunity for your designs.

Why Choose Fairchild's Optoelectronic Devices

Fairchild's high performance optocouplers offers
superior noise immunity due to our proprietary coplanar packaging technology, Optoplanar®. (See figure 1.)

  • With their high speed data rates, these optocouplers are ideal
    for high speed data communication.
  • All of ouroptoelectronics products are lead (Pb) free and RoHS compliant.
  • In addition, they are certified by major safety regulatories.
  • Available in 3.3V and 5V supply voltages.
  • Bandwidth capability of up to 15Mbit/s
  • Meet or exceed safety regulatory standards.
  • High isolation voltage up to 5kV.

Additionally, 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.
