Si photodiodes with preamp S9295 series - 1

Si photodiodes with preamp S9295 series Large area photodiode integrated with op amp and TE-cooler The 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 GΩ) 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. The S9295 series also features low noise and low NEP, and is especially suitable for NOx detection. The photosensitive area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise. Large photosensitive area: 10 × 10 mm UV to NIR Si photodiode optimized for precision photometry Compact hermetic package with sapphire window High precision FET input operational amplifier High gain: Rf=10 GΩ Low noise and NEP High cooling efficiency S9295 : ΔT=50 °C S9295-01: ΔT=30 °C High stability with thermistor Highly resistant to EMC noise The S9295 series may be damaged by Electro Static Discharge, etc. Please see Precautions in P.6.

Dew condensation on the product may cause deterioration in characteristics and reliability. *2: Ripple max.: 10% *3: S9295-01: 3.7 V Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the product within the absolute maximum ratings.

Si photodiodes with preamp Precautions ESD The S9295 series may be damaged or their performance may deteriorate by such factors as electro static discharge from the human body, surge voltage from measurement equipment, leakage voltages from soldering irons and packing materials. As a countermeasure against electro static discharge, the device, operator, work place and measuring jigs must all be set at the same potential. The following precautions must be observed during use: ∙ To protect the device from electro static discharge which accumulate on the operator or the operator,s clothes, use...
