Description
The OP705 series devices consist of NPN silicon phototransistors molded in blue tinted epoxy packages. The narrow receiving angle provides excellent on-axis coupling. These devices are 100% production tested using infrared light for close correlation with Optek’s GaAs and GaAlAs emitters.

FEATUREs
• Narrow receiving angle
• Variety of sensitivity ranges
• T-1 package style
• Small package size for space limited applications
• Base-emitter resistor provides ambient light protection
