Description
The AD2C641 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-tosource
enhancement type DMOS transistors. Total device
output resistance is guaranteed to be less than 500mΩ
making this device the ideal choice where minimal signal
attenuation is required. The device comes with up to 5kV
input to output isolation.

Features
 Compact 4 pin DIP/SMD Package
 High Isolation Voltage (up to 5kVRMS)
 Low Input Control Current (2.5mA TYP)
 200mΩ Typical On Resistance
 1A Maximum Continuous Load Current
 Long Life / High Reliability
 RoHS / Pb-Free / REACH Compliant

Applications
 Multiplexers
 Meter Reading Systems
 Data Acquisition
 Medical Equipment
 Battery Monitoring
 Home Safety / Security Systems
