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. 3 4° typ. .050 (1.27) typ. .031 (.79) typ. .150 (3.81) .130 (3.30) Radius .008 (.25) .004 (.10) .040 (1.02) .020 (.51) .100 (2.54) typ. .395 (10.03) .375 (9.52) .312 (7.80) .298 (7.52) 3° to 7° 10° .315 (8.00) typ. .010 (2.54) typ.
