Description
The ACPL-M43T is a single channel, high temperature,
high CMR, high speed digital optocoupler in a five lead
miniature footprint specifically used in the automotive
applications. The SO-5 JEDEC registered (MO-155) pack-
age 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.
This digital optocoupler uses an insulating layer between
the light emitting diode and an integrated photon 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 30kV/µs minimum at V_CM = 1500V over ex-
tended temperature range.
