This device is a single channel optically coupled solid state relay.  It consists of an LED optically coupled to a photovoltaic diode which drives two discrete power MOSFETs. The CSMR140 is being used in environments encountered by space applications. Package styles for this device include an LCC-4 surface mount package, with solder dip options available.

Absolute maximum ratings, recommended operating conditions, electrical specifications and performance characteristics are identical for all units. Any exceptions, due to packaging variations and limitations, are as noted in the datasheet.
