IR transceiver module saves redesign as a drop-in replacement

Provided as a drop-in replacement for devices from other manufacturers, the TFBR4650 is for IrDA-compliant infra red (IR) transceiver modules in the standard 6.8 x 2.8 x 1.6mm footprint. Vishay Semiconductors says the module can be used in cases of discontinuation of competitors’ parts, as a drop-in replacement and prevents any need for PCB redesigns.

The TFBR4650 consists of a PIN photodiode, infra red emitter, and control IC in a single package. It complies with the latest IrDA physical layer standard for IR data communication, says Vishay and supports data rates from 9.6 to 115.2kbits per second (SIR) for wireless transmission in gas and power meters, mobile phones, microphones, robots, and mobile medical devices.

The TFBR4650 features a link distance up to 300mm with standard IrDA and up to 200mm with low power IrDA. The low power specification can be increased to 500mm using an external resistor to set the emission intensity. Providing low power consumption, the module offers an idle supply current of 75 microA at 3.6V and a shutdown current of 10nA typical at +25 degrees C.

The lead (Pb)-free and RoHS-compliant TFBR4650 operates from 2.4 to 3.6V over a temperature range of -25 to +85 degrees C.

Samples and production quantities of the TFBR4650 IR transceiver module are available now, with lead times of eight weeks.

Vishay Intertechnology believes it is one of the largest manufacturers of discrete semiconductors (diodes, MOSFETs, and infrared optoelectronics) and passive electronic components (resistors, inductors, and capacitors). These components are used in virtually all types of electronic devices and equipment, in the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies, and medical markets.
