MOS FET Relays Technical Information Introduction New models with a wider range of characteristics provide an array of solutions, meeting the needs of today's high performance applications. Our expanded range of MOS FET relays, Type G3VM, sets the benchmark in Solid State Relays (SSRs). Products are manufactured using the latest advances in automated production and include a variety of improved construction technologies within the areas of the input LED, PDA (Photo Diode Array used as a photocoupler) and MOS FET chips used in the load switching circuit. As a result, further reductions in package size and power requirements have been achieved. Combining the advantages of mechanical and solid state technology, the new G3VM range gives you unprecedented capability to design. All models featured include a double MOS FET load circuit, enabling the designer complete versatility since it makes no difference whether an AC or DC load in either direction is connected (Connection A). Thus, the MOS FET relay is a fully functional alternative to an electromechanical relay with minimal additional drive circuitry. The built-in Current Limit Function (CLR models) has many uses. Traditionally used to clamp excessive over current fault conditions in telecom equipment, this feature can also be used to good effect to resist transient and short circuit conditions. MOS FET relays are the ideal data and telecommunication solution for line seizing, line switching, hook switching, Data Access Arrangement (DAA) function, line transformer circuit control and other feature phone functions. Central office applications require high reliability and long life. Here the G3VM is ideal for use in the areas of Subscriber Line Interfaces (SLICs) Multiplexers and Routers. In addition, Local Area Networks (LANs) and Network Termination Units (NTUs) including Set-Top Boxes (STBs) and Remote Metering Systems (RMS) can take advantage of the G3VMs' small size and low ON resistance. Advances in performance and cost reduction enable MOS FET relays to be considered as good alternatives to Reed Relays in application areas such as security motion detectors (standard and antimask PIRs), and Automated Test Equipment (ATE) probe cards.
