The C30737LH-300-7XN Series from Excelitas Technologies is available in an LLC SMD package that comes with clear glass or built-in 635 nm, 650 nm, or 905 nm filter window options.
Excelitas Technologies’ C30737LH-300-7XN Series employs a 300 µm active area silicon avalanche photodiode (APD) providing high responsivity between 500 nm and 1000 nm, as well as extremely fast rise times at all wavelengths with a frequency response up to >1 GHz. Its size allows for an easy optical assembly at the same time providing a very low capacitance <1 pF.
This APD is available in leadless, ceramic-carrier (LCC) SMD package that comes with clear glass or built-in 635 nm, 650 nm, or 905 nm filter window options. The device is available in tape-and-reel packing format which allows for SMT-compatible, RoHS-compliant reflow soldering.
It is an ideal APD device for high volume, cost-effective commercial distance-meter, range-finder, and high-speed, 3D laser scanning (LIDAR) applications.
