Overview
The low-capacitance large-area InGaAs PIN photodiode chip series uses a front-illuminated planar structure and offers Φ1mm, Φ2mm, Φ3mm, Φ5mm circular photosensitive areas and a 1.5mm×6mm rectangular photosensitive area. Some models provide low-capacitance versions, with high bandwidth, high sensitivity and high reliability for optical warning and LiDAR applications.
