Letex Technology Corp.

Photo DMOS-FET Relay

Description

The LT310 is a miniature 2-Form A solid state relay in a 8 pin SOP package that employs

optically coupled MOSFET technology to provide 1500V of input to output isolation.

The optically coupled input is controlled by a highly efficient GaAlAs infrared LED and

MOS FETs on the output side.
