Broadcom ASSR-601J 1 Form A Solid State Relays are high-voltage solid state relays designed for high voltage industrial applications. The ASSR-601J 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 10mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.4V or less.
