ACPL-K44T-000E Product Details

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 pakcage 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-K44TIPM optocouplerhave an increased common mode transient immunity of typical 30kV/µs minimum at VCM = 1500V guaranteed over extended temperature range. Broadcom R2Coupler isolation products provide the reinforced insulation and reliability needed for critical in automotive and high temperature industrial applications.
