ETC LT215 Photo dmos-fet relay Datasheet

Photo DMOS-FET Relay
Description
The LT215 is a miniature 1-Form A solid state relay in a 4 pin SOP package that employs optically
coupled MOSFET technology to provide 1500V of input to output isolation. The Input of optical
coupler been controlled by a highly efficient GaAlAs infrared LED and MOS FETs on the output side.

‧Low driver power requirements (TTL/CMOS Compatible)
‧High reliability
‧Arc-Free with no snubbing circuits
‧1500Vrms Input/Output isolation
‧Tape & Reel version available
Applications
‧Telecommunications (PC, Electronic notepad)
‧Measuring and Testing equipment
‧Industrial control
‧Security equipments
‧High speed inspection machine
