The LTV-355T is a subminiature optocoupler from Lite-On Technology Corporation, featuring a mini-flat package with a 2.0mm profile, offering a 30% smaller volume compared to conventional DIP types. It boasts a high current transfer ratio (CTR) and excellent isolation voltage (3,750Vrms) thanks to its double transfer mold technology. This product is suitable for high-density mounting applications and programmable controllers.
