IR transceiver module is a drop-in replacement for other devices

Vishay Intertechnology is presenting designers with a new device for IrDA-compliant IR transceiver modules in the standard 6.8mm x 2.8mm x 1.6mm footprint. The company's TFBR4650 provides a reliable drop-in replacement for devices from other manufacturers. In cases of discontinuation of competitors' parts, this drop-in replacement stops any need for PCB redesigns. The device comprises of a PIN photodiode, infrared emitter, and control IC in a single package. Compliant with the latest IrDA physical layer standard for IR data communication, the module supports data rates from 9.6kbit/s to 115.2kbit/s (SIR) for wireless transmission in cell phones, microphones, gas and power meters, robots, and mobile medical devices. The device features a link distance up to 30cm with standard IrDA and up to 20cm with low power IrDA. The low power specification can be increased to 50cm using an external resistor to set the emission intensity. Offering low power consumption, the module provides an idle supply current of 75µA at 3.6V and a shutdown current of 10nA typical at +25C. Lead (Pb)-free and RoHS-compliant, the device operates from 2.4V to 3.6V over a temperature range of -25C to +85C.
