PD502

PD502 is a type of stanley photo darlington transistor which has two unique features: The first one is midget resin package of 3.4 mm ida, permits use in limited space.The second one is high photo current.Besides, it also has four applications: The first one is photoelectric switch, photoelectric counter. The second one is tape and card readers. The third one is position-rotation detection. The last one is infrared  ray applied devices.

There are some absolute maximum ratings about PD502. Collector dissipation(Pc) is 60 mW. Collector-emitter breakdown voltage(VCEO) is 20 V. Emitter-collector breakdwon voltage(VECO) is 5 V. Collector current(Ic) is 20 mA. Operating temperature(Topr) is -30 to +85. Storage temperature(Tstg) is -30 to +100.Otherwise, there are some electro-optical charactersitics about it.Collector-emitter dark current(ICEO) is 1 uA max when VCE is 10 V and Ee is 0. Photo current(Ic) is 1 mA min and 4 mA typ when VCEi s 5 V , Ee is 0.01mW/cm².Peak sensitivity wavelength is 800 nm typ when Vcc is 10 V, Ic is 2 mA and RL is 100 ohms. Collector-emitter staturation voltage(VCE(sat)) is 0.7 V typ when Ic is 5 mA and Ee is 10 mW/cm².
