AD8C111
1 Form A
Solid State Relay
DESCRIPTION
The AD8C111 is a bi-directional, single-pole, single-throw, normally open multipurpose relay. It is designed to replace electro-
mechanical relays in general purpose switching applications. The relay consists of an integrated circuit that drives two rugged
drain-to-drain 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, making the relay ideal for switching lamps and
highly inductive loads.
