S9295 series is a thermoelectrically cooled Si photodiode with preamp developed for low-light-level detection. A large area photodiode, op amp,
TE-cooler and feedback resistor (10 G
) are integrated into a single package. A thermistor is also included in the same package for temperature
control so that the photodiode and I-V conversion circuit can be cooled for stable operation. S9295 series also features low noise and low NEP,
and is especially suitable for NOx detection. The active area of the photodiode is internally connected to the GND terminal making it highly
resistant to EMC noise.
