ASSR-4110-003E

The ASSR-4110 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-4110 and ASSR-4111, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual channel confi guration, ASSR-4120, are 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. Their electrical and switching characteristics are specifi ed over the temperature range of -40°C to +85°C. They are used for general purpose switching of signals and low power AC/DC loads. ASSR-4111 enables AC/DC and DC-only output connec tions. For DC-only connection, the output current, Io, increases to 0.24A and the on-resistance, R(ON) reduces to 8.5?.
