Part Identification The LH1521 dual 1 Form B relays are SPST normally closed switches that can replace electromechanical relays in many applications. They are constructed using a GaAIAs 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 circuitry, and MOSFET switches. 2000 Infineon Technologies Corp. • Optoelectronics Division • San Jose, CA www.infineon.com/opto • 1-888-Infineon (1-888-463-4636) OSRAM Opto Semiconductors GmbH & Co.
