ISP847XDG

Transistor, Photovoltaic Output Optoisolators Overview

The ISP847XDG is a high-density mounting phototransistor optically coupled isolator manufactured by Isocom Components. It features four independent channels within a single 16-pin DIP package, providing 5300Vrms isolation voltage between input and output circuits. The device utilizes infrared LEDs paired with NPN silicon phototransistors for signal transmission. Key electrical specifications include a maximum current transfer ratio of 600% at 5mA input current, with typical rise and fall times of 4µs and 3µs respectively. The output transistor supports a maximum collector-emitter breakdown voltage of 35V.
