STR8043

Random Phase

400V / 1.2A

AC Solid State Relay

Description

The STR8043 is a bi-directional, single-pole, single-throw,

normally open multipurpose relay. The device consists of

an IR LED optically coupled to a random phase switching

AC output structure. It has a high blocking voltage (400V)

and can handle continuous load currents of up to 1.2ARMS.

The STR8043 assures no false triggering under adverse

conditions.

The STR8043 comes standard in a compact 8 pin DIP

package.

The package construction makes it ideal for

high-density board applications.
