ASSR-1420-002E

The ASSR-1420-002E is a general-purpose Solid State Relay with DPST-NO contacts and through hole terminals. This ASSR-14-series form-A relay (Photo 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. The single channel configuration is equivalent to 1-form-A electromechanical relays (EMR). Used for general-purpose switching of signals and low power AC/DC loads. 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 (0.2Ω typical for DC, 0.7Ω typical for AC/DC)
• Very high output off-state impedance (10TΩs typical)
• -40 to 85°C Operating temperature range
