Description

Each OP535 consist of an NPN silicon photodarlington molded in a green plastic package. The narrow receiving angle provides excellent on-axis coupling. These devices are 100 production tested using infrared light for close correlation with OPtek GaAs and GaAlAs emitters. Photodarlington devices are normally used in applications where light single levels are low and more current gain is needed than is possible with phototransistors.

Features

• Narrow receiving angle

• T-1 package style

• High current gain

• Small package size for space limited applications
