The VISHAY TSOP41 series are miniaturized receivers for infrared remote control systems. They operate with short burst transmission codes and high data rates. The product integrates a photo detector and preamplifier, with an internal filter for PCM frequency and improved shielding against electrical field disturbance. It is compatible with TTL and CMOS, has low power consumption, and high immunity against ambient light.
The TSOP41 series are miniaturized infrared receiver modules that combine a photodiode and preamplifier in a single package with an internal PCM‑frequency filter. They provide low‑power consumption, high immunity to ambient light, and TTL/CMOS compatible low‑level output suitable for direct decoding by microprocessors.
The document includes absolute maximum ratings, electrical and optical characteristics, typical performance curves, recommended data formats, and mechanical package dimensions. It also contains Vishay’s environmental policy regarding ozone‑depleting substances.
