STZ8043

Zero Cross

400V / 1.2A

AC Solid State Relay

Description

The STZ8043 is a bi-directional, single-pole, single-throw,

normally open multipurpose relay. The device consists of

an IR LED optically coupled to a zero cross switching AC

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

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

STZ8043 assures no false triggering under adverse

conditions.

The STZ8043 comes standard in a compact 8 pin DIP

package.

The package construction makes it ideal for

high-density board applications.
