General
The TLP171J photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a 4-
pin package with 2.54-mm lead pitch and 2.1-mm height. This photorelay requires 0.2 mA of LED current to turn
it on. It is suitable for applications that need electrical power savings.
