Dual Emitter Series

Molded Lead Frame and Leadless Ceramic Substrate

Download Datasheet Technical Support Email This Page

The dual LED series consists of a 660nm (red) LED and a companion IR LED such as 880 / 895, 905, or 940nm. They are widely used for ratiometric measurements such as medical analytical and monitoring devices. They can also be used in applications requiring a low cost Bi-Wavelength light source.

Two types of pin configurations are available: 1.) three leads with one common anode or cathode, or 2.) two leads parallel back-to-back connection. They are available in two types of packaging. Clear lead frame molded side looker, and leadless ceramic substrate. The matching photodetectors' responses are optimized for maximum responsivity at 660nm as well as near IR wavelengths. They exhibit low capacitance and low dark currents and are available in three different active area sizes in the same two types of packaging as the dual emitters: Clear lead frame molded side looker and leadless ceramic substrate.
