Photodiodes & -Transistors for high-volume Applications Left: Spectrally Adapted Photodiodes and Phototransistors AMBIENT Right: C30737PH Series T-13/4 (TO-like) Through-Hole Package (4.9 mm Diameter) LIGHT SENSORS Spectrally Adapted Photodiodes and Phototransistors Applications * Interior and exterior light switching (dusk/dawn switch) * Interior and exterior light control (dimming) * Automotive headlight dimmer * Display contrast control * Energy conservation * Oil burner flame monitoring Features and Benefits * Response approaching human eye using Excelitas' IR-BLOCTM technology * Perfect light sensor in conjunction with Excelitas pyroelectric detectors for motion controlled light switches * RoHS compliant Product Description Ambient light sensors from Excelitas provide an easy solution for applications that require a response similar to the human eye, making it ideal when the response should only be influenced by visible light. These devices contribute in various applications to energy conservation in both fixed and portable devices. There are three main devices types, one being filtered photodiodes, the second filtered phototransistors and finally wavelength selective devices based on III-V material. They are available in a number of standard packages, including surface mount for automated assembly.
