S9295 series is a thermoelectrically cooled si photodiode with preamp developed for low-light-level detection. a large area pho todiode, 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 no ise and low nep, and is especially suitable for nox detection. the active area of the photodiode is internally connected to the gnd terminal mak ing it highly resistant to emc noise. features l large active area: 10 10 mm l uv to nir si photodiode optimized for precision photometry l compact hermetic package with sapphire window l high precision fet input operational amplifier l high gain: rf=10 g ? l low noise and nep l high cooling efficiency S9295 : ? t=50 ?c S9295-01: ? t=30 ?c l high stability with thermistor l highly resistant to emc noise applications l nox detection l low-light-level measurement, etc. photodiode si photodiode with preamp large area photodiode integrated with op amp and te-cooler S9295 series S9295 series may be damaged by electro static discharge, etc. please see precautions for use in the last page. absolute maximum ratings recommended operating conditions parameter symbol value parameter symbol value supply voltage (preamp) vcc 20 v supply voltage (preamp) vcc 5 to 15 v operating temperature topr -30 to +60 c te-cooler current ite 0.8 a max. storage temperature tstg -40 to +80 c thermistor power dissipation pth 0.03 mw max. te-cooler allowable voltage * 1 vte 5 v * 2 load resistance r l 100 k ? min. te-cooler allowable current ite 1 a thermistor power dissipation pth 0.2 mw *1: ripple max.: 10 % *2: S9295-01: 3.7 v electrical and optical characteristics (typ. vcc=15 v, r l =1 m ? ) S9295 S9295-01 parameter symbol condition t= -25 c t= -5 c unit spectral response range 190 to 1100 nm peak sensitivity wavelength p 960 nm feedback resistance (built-in) * 3 rf 10 g ? =200 nm 0.9 0.9 photo sensitivity s = p 5.1 5.1 v/nw output noise voltage vn dark state, f=10 hz 20 25 vrms/hz 1/2 noise equivalent power nep = p, f=10 hz 4 5 fw/hz 1/2 output offset voltage vos dark state 2 2 mv cut-off frequency fc -3 db 190 180 hz output voltage swing vo 13 v supply current icc dark state 0.3 ma thermistor resistance rth 86 30 k ? *3: custom devices are available with different rf values and/or internal cf, etc. 1
