The VISHAY TSHA440 is a high-speed infrared emitting diode with high radiant power and intensity. It is suitable for high pulse current operation and has high reliability and good spectral matching to Si photodetectors. It is commonly used in infrared remote control and free air transmission systems.
The TSHA440 series are high‑efficiency infrared emitting diodes built with GaAlAs‑on‑GaAlAs technology and packaged in a clear, untinted plastic case. They provide about 50 % higher radiant power than standard GaAs devices and are suited for high‑pulse‑current operation with good spectral matching to Si photodetectors.
