Optical Receiver Module with Large Area GaAs Photodiode

PX00S1 is a large area GaAs PD00S1 photodiode chip packaged in an 8-pin TO-5 header and capped with a flat window TO-cap. The topside illuminated p-i-n photodiode structure is optimized for monitoring applications. It offers an excellent responsivity in the wavelength region from 800 to 860 nm.

The photodiode is manufactured with a low reflectivity AR coating, which provides low back reflection and high return loss over the specified wavelength range.


  • Large topside aperture: 2 mm
  • Optimized for monitoring applications
  • High responsivity: 0.6 A/W @ 850 nm
  • Also available as bare die
