ACPL-K43T-000E
Automotive R²Coupler™ 1MBd Transistor Output Optocoupler in Stretched SO-8 Package with 8mm Creepage & Clearance

The ACPL-K43T is a single channel, high temperature, high CMR, high-speed digital automotive IPM optocoupler in an eight lead miniature footprint.  specifically used in the automotive applications.  The ACPL-K44T is a dual channel equivalent of the ACPL-K43T.  Both products are available in the stretched SO-8 package outline meeting 8mm creepage and clearance requirements, designed to be compatible with standard surface mount process

This digital IPM optocoupler uses an insulating layer between the light emitting diode and an integrated photo 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 ACPL-K43T and ACPL-K44T IPM optocouplers have an increased common mode transient immunity of typical 30kV/µs minimum at VCM = 1500V guaranteed over extended temperature range.

Avago R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications.
