The Broadcom® ASSR-15XX Series is specifically designed for high-current applications, commonly found in industrial applications.

The ASSR-15XX Series consists of an AlGaAs infrared lightemitting diode (LED) input stage that is 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 and off two discrete high-voltage MOSFETs. The relay turns on (contact closes) with a minimum input current of 3 mA 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 ASSR1511, are equivalent to 1 Form A Electromechanical Relays (EMR), and the dual-channel configurations, ASSR-1520 and ASSR-1530, 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 and true surface mount SO-8pin. Their electrical and switching characteristics are specified over the temperature range of –40°C to +85°C.

The ASSR-1511 enables AC/DC and DC-only output connections. For DC-only connections, the output current, IO, increases to 2A and the on-resistance, R(ON), reduces to 0.2Ω.
