PIN PD / MPD Chips

The Monitor Photodiode (MPD) chip, is a planar light-receiving structure and has a large photosensitive surface of 200μm. It is used in the TO-CAN package of the TO56 laser with the long wavelength range of 980nm-1620nm in optical communication to monitor the back light of the laser chip. Using the InGaAs material as the medium, MPD chip features high responsivity, low dark current, low capacitance and high electrostatic damage protection ability.
