The ACNU-250L is a single-channel fast optocoupler device in an 11-mm stretched SO-8 package. The device is equipped with an insulating layer between the LED and an integrated photon detector to provide electrical insulation between the input and the output. Having separate connections for the photodiode bias and output transistor collector reduces the base-collector capacitance and greatly enhances the data speed compared to a conventional photo-transistor coupler. It is suitable for isolated communication logic interfaces, industrial applications, renewable inverters, medical equipment, etc.
