High Current, Solid State Relay (Photo MOSFET), 60V/1.0A/0.5ohm

The ASSR-15XX Solid State Relay series is specifically designed for high current applications, commonly found in industrial applications.

The ASSR-15XX 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-1510 and ASSR-1511, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual channel configuration, ASSR-1520, 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.

ASSR-1511 enables AC/DC and DC-only output connections. For DC-only connection, the output current, Io, increases to 2A and the on-resistance, R(ON) reduces to 0.25Ω.
