OT400

The OT400 sensors feature an NPN silicon phototransistor mounted in a miniature hermetic package.The lensing effect allows an acceptance half angle of the 12 degrees measured from the optical axis to the half power point.Sensors of OT400 can be mounted into a housing or soldered directly into a printed circuit board.Here you can get some information about the features.First is miniature phototransistor.Then is hermetically sealed package.The last one is high sensitivity.

What comes next is about the absolute maximum ratings of OT400.The collector-emitter voltage is 35 V.The emitter-collector voltage is 6 V.The power dissipation is 100 mW.The storage temperature range is from -65 to +150.The operating temperature range is from -55 to +125.The lead soldering temperature (for 5 sec with soldering iron) is 240.

The following is about the electrical characteristics of OT400(25).The minimum I_C(ON) (light current) is 1 mA at H=1 mW/cm² for OT400-1.The minimum I_C(ON) (light current) is 2 mA and the maximum is 6 mA at H=1 mW/cm² for OT400-2.The minimum I_C(ON) (light current) is 4 mA at H=1 mW/cm² for OT400-3.The maximum I_CEO (dark current) is 40 nA at V_CE=10 V,H=0.The minimum V_CEO (collector-emitter voltage) is 35 V.The minimum V_ECO (emitter-collector voltage) is 6 V.The maximum V_CE(SAT) (saturation voltage) is 0.5 V at I_C=1 mA.The typical (angular response) is ±12 Deg.The typical t_r,t_f (rise time or fall time) is 3 S for OT400-1 and is 5 S for OT400-6 at R_L=100,V_CC=10 V.
