AD4C111
Dual 1 Form A
Solid State Relay
DESCRIPTION
The AD4C111 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. It is designed to replace
electromechanical relays in general purpose switching applications. The relay consists of two integrated circuits, each driving a pair of
rugged source-to-source enhancement type DMOS transistors. Each integrated circuit is 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, making the relay ideal for
switching lamps and highly inductive loads.
