Switching Characteristics

of Normally Open Devices

The TS120L integrated circuit device combines a

350V, current-limited, normally open (1-Form-A) relay

with a Darlington transistor optocoupler in a single

package. The relay uses optically coupled MOSFET

technology to provide 3750V

isolation. The efficient MOSFET switches and

photovoltaic die use Clare’s patented OptoMOS®

architecture, in which highly efficient GaAIAs infrared

LEDs control the optically coupled output.

Telecom circuit designers, using the TS120L, can

now take advantage of two discrete functions in a

single component that uses less space than

traditional discrete component solutions.
