Product Description
Product Overview
The Cosmo KPC355NT Series is a 4-pin Mini-Flat Photodarlington photocoupler. It features a gallium arsenide infrared-emitting diode optically coupled to a photodarlington. This series offers high isolation voltage (3750 Vrms) and a high current transfer ratio (CTR min. 600% at IF=1mA, Vce=2V). Its compact 4-pin SOP package with a 2.0mm profile makes it suitable for various electronic applications requiring signal transmission between circuits of different potentials and impedances.
