Description The LCB110 is a 1-Form-B relay which uses optically coupled MOSFET technology to provide 3750V of input to output isolation. The efficient MOSFET switches and photovoltaic die use Clare’s patented OptoMOS® architecture. A highly efficient GaAIAs infrared LED controls the optically coupled input. The LCB110 has low on resistance and is well suited for most applications requiring a normally closed relay. The device is available in small 6-pin dual in line package in standard though hole and surface mount lead bend.

Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability.
