AD4C541
Dual 1 Form A
Solid State Relay
The AD4C541 is a bi-directional, double-pole, single-throw, normally open solid-state relay. This device consists of two discrete relays in
a compact 8 pin package. Each relay is composed of a AlGaAs LED optically coupled to an IC--driving a pair of source-to-source
enhancement type DMOS transistors. Low on-resistance allows for a high load current rating--making the AD4C541 ideal in applications
where packaging density and high load current requirements present unique design challenges.
