No. 7980 * FIMKO Approval * CSA - Certification 093751 APPLICATIONS * General Telecom Switching - On/off Hook Control - Ring Delay - Dial Pulse - Ground Start - Ground Fault Protection * Instrumentation * Industrial Controls * See Application Note 56 DESCRIPTION The LH1500 is robust, ideal for telecom and ground fault applications. It is a SPST normally open switch (1 Form A) that replaces electromechanical relays in many applications. It is 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. In addition, it employs current-limiting circuitry which meets FCC 68.302 and other regulatory voltage surge requirements when overvoltage protection is provided. 4 .100 (2.54) .040 (1.016) .020 (0.508) .315 (8.00) min. .012 (0.31) .008 (0.20) Package Dimensions in Inches (mm) DIP Pin One ID. 3 .256 (6.50) .248 (6.30) 4 5 6 2 1 S 6 DC 5 S' 4 S S' 1 2 3 .343 (8.70) .335 (8.50) .039 (1.00) Min. 4 Typ. .020 (.051) Min. .022 (0.55) .018 (0.45) .035 (0.90) .031 (0.80) .100 (2.54) Typ. .300 (7.62) Typ. .150 (3.81) .130 (3.30) 18 Typ. .014 (.35) .010 (.25) .347 (8.82) .300 (7.62) .150 (3.81) .110 (2.79) SMD .343 (8.71) .335 (8.51) Pin one I.D. .256 (6.50) .248 (6.30) .050 (1.27) typ. .052 (1.33) .048 (1.22) .150 (3.81) .130 (3.30) .0098 (.25) .0040 (.10) .395 (10.03) .375 (9.63) .300 (7.62) typ. .039 (0.99) min. 3 to 7 18 Part Identification Part Number LH1500AT LH1500AAB LH1500AABTR Description 6-pin DIP, Thru Hole 6-pin SMD 6-pin SMD, Tape and Reel Document Number: 83804 Revision 06-March-02 www.vishay.com 3-35 Recommended Operating Conditions 140 120 Load Current (mA) 100 80 60 40 20 0 -40 -20 0 20 40 60 80 Ambient Temperature (C) IFon = 4 to 10 mA IFon = 2 mA IFon = 1 mA Absolute Maximum Ratings, TA=25C Stresses in excess of the Absolute Maximum Ratings can cause permanent damage to the device.
