Description
The ACPL-M43U is a single channel, high temperature,
high CMR, high speed digital optocoupler in a ve lead
miniature footprint specically used for industrial applica-
tions. The SO-5 JEDEC registered (MO-155) package out-
line does not require “through holes” in a PCB. This pack-
age occupies approximately one-fourth the footprint area
of the standard dual-in-line package. The lead prole is
designed to be compatible with standard surface mount
processes.
This digital optocoupler uses an insulating layer between
the light emitting diode and an integrated photon detec-
tor 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-transis-
tor coupler by reducing the base-collector capacitance.
The ACPL-M43U has an increased common mode tran-
sient immunity of 30kV/µs minimum at V
CM
= 1500V over
extended temperature range.
