Vishay Semiconductors Infrared Transceivers

Vishay Semiconductors Infrared Transceivers are small-profile Infrared Data Association (IrDA) compliant transceivers. These transceivers enable short-distance wireless data communication and support data rates up to 115kbit/s. These transceivers feature transmission distances from 50cm to 1m. The infrared transceivers have a split power supply that allows the emitter to be driven by a separate power supply. They are available in six variants: TFBR4650, TFBS4650, TFBS4652, TFBS4711, TFDU4101, and TFDU4301. The infrared transceivers are lead-free and capable of lead-free processing. Typical applications include data collection, medical, vending, Point-of-Sale (POS), and access control.

Features

  • Compliant to the latest IrDA physical layer specification (9.6kbits/s to 115.2kbit/s) 
  • Power consumption of less than 1µA in shutdown mode
  • Link distance:
    • TFDU4101 – 1m
    • TFBS4711 – 1m
    • TFBS4650 – 70cm

Applications

  • Short-distance wireless communication and data transfer:
    • White goods maintenance interface
    • Battery cell to battery cell balancing in electric vehicles
  • Environments where RF is problematic:
    • Mines
    • Hospitals
    • Data network security
