IR Emitters & Silicon PIN Photodiode

Vishay Semiconductors IR Emitters and Silicon PIN Photodiodes feature an 830nm to 950nm wavelength range with high radiant sensitivity from 1mW/sr to 1800mW/sr. These emitters provide double heterojunction infrared emitters with the lowest forward voltages and highly efficient homojunction emitters. The photodiodes offer the broadest selection of high-speed, low-dark current PIN photodiodes that are specifically designed to achieve excellent sensitivity together with high reliability.
