Automotive Solid State Relay
with R2CouplerTM Isolation
Data Sheet
Description
Features
The ASSR-601JV/JT is a high-voltage solid state relay that is
designed for automotive applications. ASSR-601JV/JT 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 10 mA through the input LED. The relay turns
off (contact opens) with an input voltage of 0.4V or less.
