IR LEDs & Photodetectors

Würth Elektronik IR LEDs and Photodetectors are designed to ensure perfect optical coupling and extremely fast switching times. These devices are offered in all industry-standard packages and in a wide range of wavelengths for design flexibility. Since the spectra and wavelengths of Würth Elektronik IR LEDs and Photodetectors match perfectly, these modules are ideally suited for data transmission. The identical design of IR LEDs and Photodetectors facilitates easier PCB design. The photodetectors are available in numerous designs with or without a daylight filter. Devices in the Würth Elektronik optoelectronics portfolio equipped with gold contacts offer excellent conductivity. The WL-SIQW series features infrared quad-frame no lead (QFN) waterclear LEDs that offer high power output, low thermal resistance and are ideal for applications such as face recognition, night vision, security cameras and gaming, and movement recognition.
