Description
The ACPL-M43T is a single channel, high temperature, high
CMR, high speed digital optocoupler in a ve lead minia-
ture footprint speci cally used in the automotive applica-
tions. The SO-5 JEDEC registered (MO-155) package outline
does not require “through holes” in a PCB. This package oc-
cupies approximately one-fourth the footprint area of the
standard dual-in-line package. The lead pro le 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-transistor
coupler by reducing the base-collector capacitance.
The ACPL-M43T has an increased common mode transient
immunity of 30kV/s minimum at V
CM
= 1500V over ex-
tended temperature range.
