InGaAs PIN photodiode
G8605 series
Thermoelectrically cooled NIR (near infrared) detector with low noise and high-speed response
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.
