The CDMR310B has two power MOSFET optocouplers packaged into a single 8-pin dual in-line (DIP) package, and is suited for applications where two independent switches are required. This popular hermetic ceramic package combined with 1,500Vdc isolation between input and output, and between two isolated relays, makes this device ideal for solid state relay applications.
Functionally, the CDMR310B operates as two SPST, normally open (2 Form “A”) solid state relays. Each relay is actuated by an input current that can be driven from a 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.
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.
