LH1503AB

LH1503AB/AAC/AACTR 2 Form A Solid State Relay FEATURES Current Limit Protection l/O Isolation, 5300 VRMS Typical RON 20 Ω Load Voltage 350 V Load Current 110 mA High Surge Capability Linear, AC/DC Operation Clean Bounce Free Switching Low Power Consumption High Reliability Monolithic Receptor SMD Lead Available on Tape and Reel AGENCY APPROVALS UL – File No. E52744 CSA – Certification 093751 VDE 0884 Approval APPLICATIONS General Telecom Switching – On/off Hook Control – Ring Delay – Dial Pulse – Ground Start – Ground Fault Protection Instrumentation Industrial Controls DESCRIPTION The LH1503 relays are DPST normally open switches (2 Form A) that can replace electromechanical relays in many applications. The relays are constructed using a GaAlAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuity, and DMOS switches. In addition, these relays employ current-limiting circuity, enabling them to pass FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided. 4° typ. .050 (1.27) typ.
