ASSR-1510-503E                                  Description

The Broadcom® ASSR-15XX Series is specifically designed for high current applications, commonly found in the industrial applications. The ASSR-15XX Series consists of an AlGaAs infrared lightemitting diode (LED) input stage optically coupled to a highvoltage 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 3 mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less.
