1 photo ic diode plastic package shaped the same as metal package www.hamamatsu.com S9648-100 the S9648-100 photo ic has spectral response close to human eye sensitivity. two active areas are made on a single chip. almost only the visible range can be measured by nding the difference between the two output signals in the internal current ampli er circuit. compared to the conventional type, the S9648-100 offers lower output uctuations for light sources producing the same il- luminance at different color temperatures. the S9648-100 is encapsulated in a plastic package having the same shape as to metal packages. the shape of the S9648-100 also resembles our 5r type visible sensors (cds photoconductive cells), so the S9648-100 can be used as a replacement for those visible sensors. absolute maximum ratings (ta=25 c) electrical and optical characteristics (ta=25 c, unless otherwise noted.) parameter symbol value unit maximum reverse voltage v r max. -0.5 to 12 v photocurrent i l 5ma forward current i f 5ma power dissipation * 1 p 250 mw operating temperature topr -30 to +80 c storage temperature tstg -40 to +85 c * 1: derate power dissipation at a rate of -3.3 mw/c above ta=25 c. parameter symbol condition min. typ. max. unit spectral response range - 300 to 820 - nm peak sensitivity wavelength p - 560 - nm dark current i d v r =5 v - 1.0 50 na photocurrent i l v r =5 v, 2856 k, 100 lx 0.18 0.26 0.34 ma rise time * 2 tr 10 to 90 %, v r =7.5 v r l =10 k ? , =560 nm - 6.0 - ms fall time * 2 tf 90 to 10 %, v r =7.5 v r l =10 k ? , =560 nm - 2.5 - ms features applications energy-saving sensor for tvs, etc. light dimmers for liquid crystal panels various types of light level measurement spectral response close to human eye sensitivity is attained without using visual-compensated lter. operation just as easy to use as a photodiode lower output-current uctuations compared with phototransistors and cds photoconductive cells. low output uctuations for light sources producing the same illuminance at different color temperatures excellent linearity
