Description

The AD4C312 is composed of two distinct 1 Form B

(normally closed) relays in one compact 8 pin DIP package.

Each relay consists of an AlGaAs LED optically coupled to

a Photo Diode Array, driving a pair of rugged source-tosource

depletion type DMOS transistors. 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.
