The PTSMD3528 is an ambient light detector and photosensor designed as a replacement for CdS photoresistors. It offers linear output with light intensity variations, good temperature stability, low dark current, and low operating illuminance. Its spectral response is similar to the human eye due to a special filtered epoxy resin package. This product is RoHS compliant, lead-free, and cadmium-free.
