ASSR-V621-302E

The ASSR-V62X Series is specially designed to drive high power MOSFETs. It consists of an AlGaAs infrared lightemitting diode (LED) input stage optically coupled to an output detector circuit. The detector consists of a highspeed photovoltaic diode array and driver circuitry to switch on/off two discrete high voltage MOSFETs externally. The relay driver turns on (contact closes) with a minimum input current of 3mA through the input LED. The relay driver turns off (contact opens) with an input voltage of 0.8V or less. The dual channel configurations, ASSR-V621, allow 2 independent MOSFETs to be driven. It has the versatility to double the photovoltaic voltage by connecting the 2 channels in series or to double the short circuit current by connecting the 2 channels in parallel. They are available in 8-pin DIP and Gull Wing Surface Mount packages.
