AD4C321

DISCONTINUED

Description

The AD4C321 is a bi-directional, double-pole, single-throw, normally open multipurpose solid-state relay. AD4C321 is designed to replace electromechanical relays in general purpose switching applications. The relay AD4C321 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 AD4C321 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.
