Description

The CQMR310 has four power MOSFET optocouplers packaged into a single 32-pin Flatpack package, and is suited for applications where four independent switches are required.  This popular hermetic ceramic package combined with 1,500Vdc isolation between input and output, and between four isolated relays, makes this device ideal for solid state relay applications.

The CQMR310 is available over the full military temperature range, with quality and screening levels ranging from Commercial and Industrial, to Defence and Space.  Gold plated leads are standard. However, other lead finishes per MIL-PRF-38534 are also available.

Functionally, 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.
