MOC8103SMT&R

Transistor, Photovoltaic Output Optoisolators Overview

The MOC8103SMT&R is a surface-mount optically coupled isolator manufactured by Isocom Components. It integrates an infrared emitting diode and an NPN silicon phototransistor within a standard 6-pin dual in-line plastic package, featuring an unconnected base pin to enhance noise immunity in high EMI environments. The device provides a high isolation voltage of 5.3 kVrms and 7.5 kV peak. Key electrical parameters include a maximum forward current of 50 mA, a collector-emitter breakdown voltage of 80 V minimum, and a typical rise time of 2 µs with a fall time of 11 µs. The current transfer ratio ranges from 40% to 80%, supporting reliable signal transmission between systems operating at different potentials and impedances.
