Product Description

Product Overview

The MTLP181 is a compact surface-mount optocoupler designed for high-density surface-mount applications, such as programmable controllers. It comprises a gallium arsenide light-emitting diode and a phototransistor, offering a smaller footprint than DIP packages. Key features include a wide current transfer ratio (CTR) range, high input-output isolation voltage, and a robust operating temperature range.
