LH1544AAC, LH1544AACTR, LH1544AB Vishay Semiconductors Dual 1 Form A Solid State Relay (Low Capacitance) FEATURES DIP S1 S1 Dual channel, LH1541 type Low capacitance switch (5 pF) Isolation test voltage 5300 V RMS S2 S2 Extremely high off-resistance Load voltage 200 V S1 S1 S2 S2 Clean bounce free switching SMD 8675 Low power consumption High reliability monolithic detector Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC i179034 2 i179034 9 1324 APPLICATIONS V DE Instrumentation - Thermocouple switching DESCRIPTION - Analog multiplexing These dual SSRs (LH1544, dual 1 form A) are SPST normally Reed relay replacement open switches which can replace electromechanical relays Programmable logic controllers in many applications. The relays provide a low-capacitance, Data acquisition high-voltage switch contact with high off-resistance and low Test equipment switch-offset voltage. These characteristics, combined with high-speed actuation, result in an SSR which is ideal for small signal and DC instrumentation applications. AGENCY APPROVALS The relays are constructed by using a GaAlAs LED for actuation control and an integrated monolithic die for the UL1577: file no. E52744 system code H, double protection switch output. The die is comprised of a photodiode array, switch-control circuity, and low-capacitance MOSFET CSA: certification no. 093751 switches.
