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.
