Turn-o Circuit ASSR-4118 , ASSR-4119 and ASSR-4128 Form A, Solid State Relay (Photo MOSFET) (400V/0.10A/35) Data Sheet Description Features Compact Solid-State Bi-directional Signal Switch The ASSR-41XX Series consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled Single and Dual Channel Normally-off Single-Pole- to a high-voltage output detector circuit. The detector Single-Throw (SPST) Relay consists of a high-speed photovoltaic diode array and 400V Output Withstand Voltage driver circuitry to switch on/off two discrete high volt- 0.1A or 0.2A Current Rating age MOSFETs. The relay turns on (contact closes) with a (See Schematic for ASSR-4119 Connection A and B) minimum input current of 3mA through the input LED. Low Input Current: CMOS Compatibility The relay turns off (contact opens) with an input voltage Low On-Resistance: 8 Typical for DC-only, of 0.8V or less. 25 Typical for AC/DC The single channel confi gurations, ASSR-4118 and ASSR- High Input-to-Output Insulation Voltage 4119, are equivalent to 1 Form A Electromechani cal Re- (Safety and Regulatory Approvals Pending) lays (EMR), and the dual channel confi guration, ASSR- - 3750 Vrms for 1 min per UL1577 4128, is equivalent to 2 Form A EMR. They are available - CSA Component Acceptance in 4-pin SO, 6-pin DIP, 8-pin DIP and Gull Wing Surface Mount for DIP packages. ASSR-4119 enables AC/DC and Functional Diagram DC-only output connections. For DC-only connection, Opto-isolation the output current, Io, increases to 0.2A and the on-re- sistance, R(ON) reduces to 10. 1 4 Truth Table Applications LED Output Telecommunication Switching ff Off Open Data Communications On Close Industrial Controls 2 3 Medical Security Single Channel, SPST Relay, 1 Form A in 4-Pin SO Package EMR / Reed Relay Replacement CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD.TurnTurn-off-off CircuitCircuit Ordering Information ASSR-xxxx is UL Recognized with 3750 Vrms for 1 minute per UL1577 and is approved under CSA Component Accept- ance Notice 5.
