Letex Technology Corp.

Photo DMOS-FET Relay

Description

The LT418 is a 1-Form A solid state relay in an 4 pin DIP package that employs optically

coupled MOSFET technology to provide 3750V 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.

Features

•Low driver power requirements (TTL/CMOS Compatible)

•No moving parts

•High reliability

•Hi-A : Load Current = 2.5A

•Arc-Free with no snubbing circuits

•3750Vrms Input/Output isolation

Applications

•Telecommunications (PC, Electronic notepad)

•Measuring and Testing equipment

•Industrial control

•Security equipments

•High speed inspection machine
