Laser Components has announced that its new range of inexpensive silicon avalanche photodiodes (APDs) come in an SMD housing. These APDs are optimised for wavelength ranges between 400nm and 1,100nm, with the dimensions 3.1 x 1.8 x 1mm. Responsivity is optimised for 905nm pulsed laser diodes.

The SAH series is based on epitaxial structure with short rise times from 250ps to 300ps, and is available in active area diameters of 230µm and 500µm. These APDs feature extremely low noise and high quantum efficiency. With a large multiplication gain and wide operating temperature range, these APDs are particularly suited for optical communication systems, speed measurement, laser radar guns, and security scanners, as well as for use in test and measurement systems in industry and medicine.
