AD2C941

1 Form A

60V / 2.5 Amp

MOSFET Output Solid State Relay

Description

The AD2C941 is a bi-directional, single-pole, single-throw,

normally open multipurpose solid-state relay. It is designed

to replace electromechanical relays in general purpose

switching applications. The relay consists of an IR LED

optically coupled to an IC that drives two rugged source-to-

source enhancement type DMOS transistors. The device

has an extremely low on resistance (75mΩ TYP) allowing it

to switch loads of up to 2.5 amps. The device comes with

up to 5kV input to output isolation.

The AD2C941 comes standard in a compact 4 pin DIP

package making it ideal for high-density board applications.
