Product Description

Product Overview

The KTP357 series is a phototransistor optocoupler featuring an infrared emitting diode optically coupled to a phototransistor detector. Encased in a compact 4-pin SOP package with a 2.0 mm profile, these devices offer high isolation voltage, halogen-free compliance, and adherence to EU REACH and RoHS standards. They are suitable for signal transmission between circuits of different potentials and impedances, making them ideal for DC converters, programmable controllers, and telecommunication equipment.
