The TFDS6500-TR3 is a Vishay Semiconductors infrared (IR) receiver module designed for remote control systems and similar applications. This component integrates a photodiode, preamplifier, and filter into a single compact package, providing high sensitivity to IR signals while effectively rejecting ambient light and noise. It is specifically designed for Pulse Code Modulation (PCM) infrared remote control systems.

Applications:

• Remote control receivers (TVs, DVD players, set-top boxes)
• Wireless audio systems
• Light curtain systems
• Proximity sensing applications
• Industrial control systems

Features:

• Compact surface-mount package
• High sensitivity to IR radiation

• Reduced false triggering from ambient light
• Low power consumption suitable for battery-powered devices
• Simplified circuit design due to integrated components

The TFDS6500-TR3 is designed to receive IR signals modulated at a specific carrier frequency, enhancing its ability to filter out unwanted noise and interference. The integrated filter is tuned to the PCM frequency, which is commonly used in IR remote control protocols. This ensures that only valid remote control signals are detected. Its low supply voltage operation makes it energy-efficient, which is particularly important in battery-powered applications. The surface-mount package allows for easy and automated assembly on printed circuit boards, reducing manufacturing costs.
