It is an SPST normally open switch (1 form A) that replaces electromechanical relays in many applications. It is constructed using a GaAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS technology, is comprised of a photodiode array, switch control circuitry and MOSFET switches. In addition, it employs current-limiting circuitry which meets lightning surge testing as per ANSI/TIA-968-B and other regulatory voltage surge requirements when overvoltage protection is provided. • Compliant to RoHS Directive 2002/95/EC and in accordance to WEEE 2002/96/EC APPLICATIONS • General telecom switching - On/off hook control - Ring relay - Dial pulse - Ground start - Ground fault protection • Instrumentation • Industrial controls Note • See “solid-state relays” (application note 56) AGENCY APPROVALS UL1577: file no.
