1 Form A
Solid State Relay
DESCRIPTION
The AD8C311 is a bi-directional, single-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 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 5A of inrush current, making the relay ideal for switching lamps and highly
inductive loads.
