Description
The M231 is a bi-directional, single-pole, single-throw,
normally open multipurpose solid-state relay in a miniature
4-pin small outline package. With a high blocking voltage
(250V) and low on-resistance, it is ideally suited to high
voltage applications requiring higher load currents. The
relay consists of an integrated circuit that drives two rugged
source-to-source enhancement type DMOS transistors –
optically coupled to a light emitting diode. The output MOS
transistors are protected with free-wheeling diodes that can
handle up to 1.5A of inrush current
