ASSR- High Current, Form A, Solid State Relay (MOSFET) (V/.A/.Ω) Data Sheet Description The ASSR- is specifically designed for high current applications, commonly found in the industrial equipments. The relay is a solid-state replacement for single-pole, normally-open, ( Form A) electromechanical relays. The ASSR- consists of an AlGaAs infrared light-emitting 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 ma through the input LED. The relay turns off (contact opens) with an input voltage of.8v or less. The ASSR- connection A, as shown in the schematic, allows the relay to switch either ac or dc loads. The connection B, with its advantages of reduced on-resistance and higher output current, allows the relays to switch dc loads only. The electrical and switching characteristics are specified over the temperature range of - C to +8 C.

For derating, refer to Figure and.. The voltage across the output terminals of the relay should not exceed this rated withstand voltage. Over-voltage protection circuits should be added in some applications to protect against over-voltage transients.. Device is considered as a two terminal device: pins,, and shorted together and pins,, and 7 shorted together.. The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. For the continuous voltage rating refer to the IEC/EN/DIN EN 77-- Insulation Characteristics Table (if applicable), your equipment level safety specification, or Avago Application Note 7, Optocoupler Input-Output Endurance Voltage.. During the pulsed R (ON) measurement ( I O duration ms), ambient (T A ) and case temperature (T C ) are equal.. For the transient rejection measurements, refer to Avago whitepaper, AV-EN, Solid State Relay Transient Immunity.
