ISQ5

Transistor, Photovoltaic Output Optoisolators Overview

The ISQ5 is a high-density phototransistor optically coupled isolator manufactured by Isocom Components. It integrates an infrared light emitting diode with an NPN silicon photo transistor within a space-efficient dual in line plastic package. The device provides a minimum collector-emitter breakdown voltage (BVCEO) of 70V and supports a high isolation voltage rating of 5.3kVRMS, with a peak withstand capability of 7.5kVPK. This configuration ensures reliable signal transmission between systems operating at different potentials and impedances.
