ISP814XG

Transistor, Photovoltaic Output Optoisolators Overview

The ISP814XG is a single-channel optocoupler from the ISP series, featuring an AC or polarity-insensitive input and a phototransistor output. It utilizes two infrared LEDs connected in inverse parallel to enable direct AC drive without external rectification. The device offers high isolation voltage of 5.3kVrms and operates within a temperature range of -30°C to 100°C. Key electrical parameters include a typical forward voltage of 1.2V, maximum collector-emitter voltage of 35V, and a current transfer ratio ranging from 20% to 300%. It is housed in a 4-pin PDIP package.
