LT433 - Photo DMOS-FET Relay

General Description

The LT433 is a miniature 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.

Key Features

Low driver power requirements (TTL/CMOS Compatible).
No moving parts.
High reliability.
Arc-Free with no snubbing circuits.
3750Vrms Input/Output isolation.
