Description
The ACNT-H511 is a single-channel open-collector output optocoupler in Stretched SO8 footprint. It uses an insulating layer between the light emitting diode and an integrated photon detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base-collector capacitance.
The ACNT-H511 with 15-mm creepage/clearance and high voltage insulation capability is suitable for isolated communication logic interface and control in high-voltage power systems such as 690VAC drives, renewable inverters, and medical equipment.
