Product Description

Product Overview

The MPC357X is a compact surface-mount optocoupler designed for high-density applications. It integrates a gallium arsenide light-emitting diode with a phototransistor, offering excellent input-output isolation. Its small footprint makes it ideal for surface-mount production and high-density installations, such as in programmable controllers. Key features include a wide current transfer ratio (CTR) range, high isolation voltage, and a robust collector-emitter breakdown voltage. The MPC357X is suitable for a variety of applications including switching power supplies, smart meters, industrial control systems, measurement instruments, office equipment like copiers, and home appliances such as air conditioners and fans.
