TFDU4203 Vishay Semiconductors Integrated Low Profile Transceiver Module for Telecom Applications – IrDA Standard Description The miniaturized TFDU4203 is an ideal transceiver for applications in telecommunications like mobile phones and pagers. The device is mechanically designed for lowest profile with a height of only 2.8 mm. The infrared transceiver is compatible to the IrDA® IrPHY specification up to a data rate of 115 kbit/s. The transceiver can be operated without external current limiting resistor to achieve full SIR compliance (range > 1 m in full ±15° cone). Features D Package Dimension: L 7.1 mm x W 4.7 mm x H 2.8 mm D Compatible to the latest IrDA IrPHY Standard D CIR Remote Control Operation: Typical Transmission Range 8 m Using Standard RC–Receivers. Receives RC–Commands with Typical Specified Sensitivity. D SMD Side View D Lowest Power Consumption 65 µA, Receive Mode, 0.01 µA Shutdown Current D Built-in Current Limitation D Output Intensity Adjustable beyond IrDA Low Power D Supply Voltage Range (2.4 V to 5.5 V) D Operational down to 2.0 V D Fewest External Components D Eye Safety: Double Safety Measures: Limited Optical Output Pulse Duration Limited Optical Output Intensity IEC60825–1, 2001: Class 1 D Tri–State Output (Rxd) D High EMI Immunity D SD Pin Applications Mobile Phones, Pagers, Personal Digital Assistants (PDA), Handheld Battery Operated Equipment Package TFDU4203 µFace Side View weight: 0.10 g Document Number 82542 Rev.

Current level can be reduced by an external resistor Internally current controlled to cover extended range of 70 cm. Current level can be reduced by an external resistor Internally current controlled to cover extended range of 70 cm. Current level can be reduced by an external resistor Low Power SIR as e.g. TFDU4201, pairs of TFDU4202 operate typically up to full IrDA SIR distance >1 m Low Power SIR as e.g. TFDU4201, pairs of TFDU4203 operate typically up to full IrDA SIR distance >1 m One power supply only Low Power SIR as e.g. TFDU4201, pairs of TFDU4204 operate typically up to full IrDA SIR distance >1 m Split power supply*) can be used when operated at higher IRED current levels *) Split power supply: The receiver circuit only is connected to a regulated power supply. The high IRED current can be supplied by a less controlled power line or directly from the battery. That feature saves power supply costs. TELEFUNKEN introdused this feature as the world first with the 4000 series Depending on the designs different applications need an optical feedback for test purposes or must be quiet (e.g. in Windows CE® applications). **) www.vishay.com 2 (12) Document Number 82542 Rev.
