Descripon:
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 Emier for low light signal rejecon. All of the devices are molded in a blue-nted 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 applicaons 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 relavely even
recepon over a large area.
Devices are 100% producon tested, using infrared light for close correlaon with Optek’s GaAs and GaAIAs emiers.
Please refer to Applicaon Bullens 208 and 210 for addional design informaon and reliability (degradaon) data.
Please see your OPTEK representave for custom versions of these devices.
