OS3302

OS3302 is a visible light cutoff type photosensor which uses a GaAs infrared emitting and high-sensitivity Si phototransistor.The small size makes it suitable for PCB mounting and for use inside equipment.Here you can get some information about the features of OS3302 .First is compact and lightweight.Then is simple structure which is suitable for a wide range of applications.The last one is designed for immunity to stray ambient light.The typical applications include timing position detection for rotating machinery such as copies and printers,start/end detection for cassette and VTR tape equipment,automatic control equipments and photoelectric counters and switches.

What comes next is about the maximum ratings of OS3302(T_a=25).First is for light-emitting side.The I_F (forward current) is 50 mA.The V_R (reverse voltage) is 5 V.Then is for light-receiving side.The V_CEO (collector-emitter voltage) is 30 V.The V_ECO (emitter-collector voltage) is 5 V.The I_C (collector current) is 50 mA.The P_C (collector power dissipation) is 75 mW.The T_opr (operating temperature) is from -25 to +85.The T_stg (storage temperature) is from -30 to +100.

The following is about electrical characteristics of OS3302 (T_a=25).First is for light-emitting side.The minimum V_F (forward voltage) is 1.00 V,the typical is 1.15 V and the maximum is 1.30 V at I_F=10 mA.The maximum I_R (reverse current) is 10A at V_R=5 V.The typical C_t (pin-to-pin capacitance) is 30 pF at V=0,f=1 MHz.Then is for light-receiving side.The typical I_D (I_CEO) (dark current) is 5 nA and the maximum is 100 nA at V_CE=24 V,I_F=0.The typical C_t (pin-to-pin capacitance) is 13 pF at V=0,f=1 MHz.Next is about the transmitting characteristics.The minimum I_C (collector current) is 0.5 mA and the typical is 2.0 mA at I_F=20 mA,V_CE=5 V.The typical V_CE(sat) (collector-emitter saturation voltage) is 0.1 V and the maximum is 0.4 V at I_F=20 mA,I_C=0.25 mA.The typical t_r (rise time) is 6s and the typical t_f (fall time) is 6s at V_CC=5 V,I_C=2 mA,R_L=100.
