The CDMR310x is two power MOSFET optocouplers in a single 8 pin dual-in-line package, suitable for applications where two independent switches are required. This popular hermetic ceramic package combined with 1500VDC isolation between input and output and between two isolated relays, makes this device ideal for solid state relay applications. The CDMR310x is available over the full military temperature range and with quality levels ranging from Commercial & Industrial to Defence and Space including any custom screening requirements. Gold plated leads are standard, but the other lead finishes per Mil-PRF-38534 are also available.

Functionally, the CDMR310x operates as two SPST, normally open (2 Form “A”) solid state relays. Each relay is actuated by an input current, and this can be driven from standard TTL device. The input current bodes a light emitting diode that is optically coupled to an integrated photovoltaic diode array. The photovoltaic diode array energises control circuitry that operates the output MOSFET.
