General Purpose, 1 Form A, Solid State Relay (Photo MOSFET), 250V/0.2A/10ohms

The ASSR-32XX Solid State Relay series consist 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-3210 and ASSR-3211, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual channel configuration, ASSR-3220, 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. Their electrical and switching characteristics are specified 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-3211 enables AC/DC and DC-only output connections. For DC-only connection, the output current, I_o, increases to 0.4A and the on-resistance, R_(ON) reduces 2.5Ω.
