PHOTODIODE

InGaAs PIN photodiode

Thermoelectrically cooled NIR (near infrared) detector with low noise and high-speed response

G8605 series

Features

l High-speed response

l Low noise

l Various active area sizes available from φ1 to φ5 mm

Applications

l Optical power meter

l Water content analyzer

l Laser diode life test

InGaAs PIN photodiodes have small terminal capacitance for high-speed response and also feature high shunt resistance and very low noise.

G8605 series of InGaAs PIN photodiodes are thermoelectrically cooled types that decrease the dark current to achieve high D*. One-stage (-10 ˚C)

and two-stage (-20 ˚C) thermoelectrically cooled types are provided.
