STS710 Overview
The STS710 is a multi-function telemunications switch. It bines a 1 Form A solid state relay, phototransistor, zener diode, darlington transistor and a bridge rectifier in a 16-pin SOIC package.The solid state relay is prised of an infrared LED optically coupled to a Photo Diode Array that drives two back-to-back MOSFETs. The optocoupler consists of back-to-back infrared LEDs coupled to a Photo-Transistor.
