●The ASSR-12XX Solid State Relay (SSR) series 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 3mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less.
●The single channel configurations, ASSR-1218 and ASSR-1219, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual channel configuration, ASSR-1228, is equivalent to 2 Form A EMR. They are available in 4-pin SO, 6-pin DIP, 8-pin DIP and Gull Wing Surface Mount for DIP packages.
●The ASSR-1219 enables AC/DC and DC-only output connections. For DC-only connection, the output current, Io, increases to 0.4A and the on-resistance, R(ON) reduces to 2.5Ω.
