TLP181
Toshiba America Electronic Components
TLP181 consist of a photo transistor optically coupled to a gallium arsenide infrared emitting diode. Since TLP181 is smaller than DIP package, its suitable for high-density surface mounting applications such as programmable controllers.
Currently the TLP181 is sourced by Toshiba and second-sourced by Opto, Inc.
Devices with similar characteristics include: IS357, PC357, PS2701, and TLP121.
