ACPL-M43T-000E
Automotive 1MBd Transistor Output Optocoupler

The ACPL-M43T is a single channel, high temperature, high CMR, high-speed digital automotive optocoupler in a five lead miniature footprint.

The SO-5 JEDEC registered (MO-155) package outline does not require “through holes” in a PCB. This package occupies approximately one-fourth the footprint area of the standard dual-in-line package. The lead profile is designed to be compatible with standard surface mount processes.

The ACPL-M43T has enhanced features to meet  automotive application environments. This diode-transistor optocoupler houses a new AlGaAsP for higher LED reliability and longer operating life with reduce output drive current.

This digital automotive optocoupler uses an insulating layer between the light emitting diode and an integrated IC 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-M43T has an increased common mode transient immunity of typical 30kV/µs minimum at Vcm = 1000V guaranteed over extended temperature range.
