The TLP240A and TLP240AF photorelay consist of a photo MOSFET optically coupled to an infrared LED. They
are housed in a 4-pin DIP package. They provide an isolation voltage of 5000 Vrms, making them suitable for
applications that require reinforced insulation.
For details, see "Devices in Halogen-Free Resin Packages" at the end of this datasheet.
