www.roithner - laser.com 1 uv - tiamo description the uv - tiamo devices are using modern hybride technology to cancel unwanted signal disturbances caused by moisture or electromagnetic radiation. the stable 0?5v output voltage can be directly connected to a spc controller or a voltage multimeter. no external amplifier is needed. the photodetectors wo rk with a sic sensing chip. sic provides the unique property of extreme radiation hardness, near - perfect visible blindness, low dark current, high speed and lo w noise. these features make sic the best available material for visible blind semiconductor uv detectors. maximum ratings (t = 25c ) parameter symbol values unit min. max. operating temperature t opr - 2 5 + 85 c storage temperature t stg - 40 + 1 00 c soldering temperature (max. 3 s) t sol + 300 c general ch aracteristics (t = 25c ) parameter symbol values unit min. * typ. * max. * supply voltage v supply 2.5 5.0 v saturation voltage v sat v supply - 5% v dark offset voltage v offset 50 v current consumption i 150 a bandwidth ( - 3 db) 15 hz risetime (10 - 90 %) (other ris e times on demand) t rise 0,066 s temperature coefficient t c - 0. 3 %/k spectral c haracteristics (t = 25c ) parameter symbol values unit min. * typ. * max. * sensitivity at peak s max 280 mv/nw/cm 2 wavelength of max. spectral sens . max 290 nm sensit ivity range (s=0.1*s max ) - 2 27 36 0 nm visible blindness (s max / s >405nm ) vb 10 10 - v 3.0
