ACNT-H50L
1-MBd Optocoupler in 15-mm Stretched SO8 Package
Data Sheet
Description
The ACNT-H50L is a single-channel 1-MBd 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-H50L 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 690V_AC drives, renewable inverters, and
medical equipment.
