OP505, OP505W, OP506, OP506W
T-1 package style
Variety of sensitivity ranges
Choice of narrow or wide receiving angle
Small package size ideal for space-limited applications
0.050” [1.27mm] or 0.100” [2.54mm] Lead spacing
OP505, OP535, OP705
Each OP505 and OP506 devices consist of an NPN silicon phototransistor, the OP535 device consist of an NPN silicon
photodarlington transistor and the OP705 device consist of an NPN silicon phototransistor with a large value resistor
integrated between the Base and Emitter for low light signal rejection. All of the devices are molded in a blue-tinted T-1
(3mm) epoxy package
The OP505, OP535 and OP705 devices have a narrow receiving angle that provides excellent on-axis coupling while the
OP506 device has a wider receiving angle for those applications where a narrow receiving angle of the OP505, OP535 and
OP705 is not required. The OP505W and OP506W device have the widest receiving angle and provides relatively even
reception over a large area.
Devices are 100% production tested, using infrared light for close correlation with Optek’s GaAs and GaAIAs emitters.
Please refer to Application Bulletins 208 and 210 for additional design information and reliability (degradation) data.
Please see your OPTEK representative for custom versions of these devices.
Interruptive applications to detect media which is semi-
transparent to infrared light
