MCT2EFM

Transistor, Photovoltaic Output Optoisolators Overview

The MCT2EFM is a single-channel phototransistor output optocoupler manufactured by onsemi. It features a 6-pin SOIC surface-mount package and provides high-voltage isolation of 7500Vrms between input and output circuits. The device utilizes an infrared LED for signal transmission and an NPN phototransistor with a base lead for detection. Key electrical characteristics include a maximum collector-emitter voltage of 30V, a minimum current transfer ratio of 20% at 10mA forward current, and a typical rise time of 2μs. It operates within a temperature range of -40°C to 100°C.
