The ASSR-40xC Solid State Relays (SSRs) are specifically designed for fast switching applications, commonly found in test and measurement systems. The low C x R and low output off-state leakage current provide higher system throughput and reduce system errors. The dual channel configuration of ASSR-402C is equivalent to 2 Form A Electromechanical Relays (EMR). One channel of the relay consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to a high-voltage output detector circuit. The detector consists of a high-speed photovoltaic diode array and driver circuitry to switch on/off two discrete high voltage MOSFETs. The relay turns on (contact closes) with a minimum input current of 1mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less.ASSR-401C is available in 4-pin SO package and ASSR-402C is available in 8-pin DIP and Gull Wing Surface Mount packages. Their electrical and switching characteristics are specified over the temperature range of -40°C to 85°C.
