AD4C112
Dual 1 Form B
Solid State Relay
The AD4C112 is composed of two distinct 1 Form B (normally closed) relays in one compact 8 pin DIP package. Each relays consists of
an AlGaAs LED optically coupled to a Photo Diode Arra, driving a pair of rugged source-to-source depletion type DMOS transistors. 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.
