ASSR-5211-301E

The ASSR-5211-301E is a High Current Solid State Relay with SPST-NO contact and surface mount terminals. This ASSR-5211-series 1-form-A relay (MOSFET) with an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to a high-voltage output detector circuit. The detector with 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 3mA through the input LED. The relay turns off (contact opens) with an input voltage of 0.8V or less. Their transient immunity of more than 1kV/µs and excellent noise rejection between input-output as well as between open terminals on the output will laminate undesirable transient effects.

• Compact solid-state bi-directional signal switch
• High-speed optically isolated MOSFET output
• Reinforced insulation of 3.75kV with fast switching speed
• Low on-resistance (2.5R typical for DC, 10R typical for AC/DC)
• -40 to 85°C Operating temperature range
