AD2C841

1 Form A

50V / 100mΩ

MOSFET Output Solid State Relay

Description

The AD2C841 is a bi-directional, single-pole, single-throw,

normally open multipurpose solid-state relay. It is designed

to be a cost-effective replacement of reed relays in low

voltage applications. The AD2C841 has an extremely low

on resistance of 70m

 (TYP) and a very high continuous

load current rating of up to 2.5A. Because the output MOS

transistors have extremely low on resistance, the device is

ideal where minimal signal attenuation is desired.

The AD2C841 comes standard in a miniature 4 pin DIP

package making it ideal for high-density board applications.
