Vishay has upgraded its TFBS4xx and TFDU4xx series of IR transceiver modules for IrDA® applications. Offered in top- and side-view surface-mount packages, the enhanced solutions provide drop-in, plug-and-play replacements for existing devices in the series while offering 20% longer link distance and improved ESD robustness to 2 kV. The transceivers support data rates up to 115.2 kbit/s (SIR) and link distances of 1 meter for wireless communication and data transmission in energy meters and monitors, industrial automation controls, mobile phones, and medical equipment. To increase battery life in portable devices, the modules offer low power consumption with an idle supply current of less than 70 μA, down to less than 1 μA in shutdown mode. Devices in the TFBS4xxx and TFDU4xxx series each consist of a PIN photodiode, infrared emitter (IRED), and low-power control IC in a single package. By upgrading the IR transceivers with Vishay’s latest in-house IC and surface emitter chip technology, the company is assuring the long-term availability of IRDC products for its customers. As drop-in replacements for existing devices, the modules help save costs by eliminating the need for PCB redesigns.
