Overview
The TLP187 is a photocoupler device manufactured by Toshiba Semiconductor and Storage. It is designed as a Darlington output type, consisting of an infrared LED optically coupled to a Darlington transistor. This device is housed in a SO6 package and is known for its high noise immunity and high insulation characteristics. The TLP187 is particularly suitable for applications requiring high breakdown voltage between the collector and emitter, such as in 100 VDC output modules of programmable controllers.
