The TLP181(GB-TPL) is a Photorelay manufactured by Toshiba Semiconductor and Storage. It is designed to provide galvanic isolation and efficient switching. It utilizes a GaAlAs infrared light-emitting diode (LED) at the input, optically coupled to a MOSFET at the output. This configuration allows the output circuit to be controlled without a direct electrical connection, thus ensuring high isolation voltage and noise immunity.
