The relays require a minimal amount of LED drive current to operate, making it ideal for batterypowered and power consumption sensitive applications. The relay 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, comprised of a photodiode array, switch-control circuitry, and MOSFET switches. In addition, the relay employs current-limiting circuitry, enabling it to pass FCC 68.302 and other regulatory surge requirements when overvoltage protection is provided. The relay can be configured for ac/dc or dc-only operation. 2001 Infineon Technologies Corp. * Optoelectronics Division * San Jose, CA www.infineon.com/opto * 1-888-Infineon (1-888-463-4636) 3-114 March 26, 2000-17 Package Dimensions in Inches (mm) DIP pin one ID S1 S1' S2 7 6 S2' 5 S1 S1' 4 .268 (6.81) .255 (6.48) 5 3 2 1 8 6 7 8 1 2 3 4 S2 S2' .390 (9.91) .379 (9.63) .045 (1.14) .030 (0.76) 4 typ. .150 (3.81) .130 (3.30) .050 (1.27) .022 (.56) .018 (.46) .035 (.89) .020 (.51) .100 (2.54) typ. .031 (0.79) .300 (7.62) typ. 10 3-9 .012 (.30) .008 (.20) .250 (6.35) .230 (5.84) .130 (3.30) .110 (2.79) SMD Pin one I.D. .268 (6.81) .255 (6.48) .390 (9.91) .379 (9.63) .031 (.79) typ. .150 (3.81) .130 (3.30) .395 (10.03) .375 (9.52) .312 (7.80) .298 (7.52) 3 to 7 .045 (1.14) .030 (0.78) Radius 4 typ. .050 (1.27) typ. .008 (.25) .004 (.10) .040 (1.02) .020 (.51) .100 (2.54) typ. 10 .315 (8.00) typ. .010 (2.54) typ.

Leakage current must be considered when designing a circuit to turn on and off these relays. Figure 19 shows a typical logic circuit for providing LED drive current. R1 is the input resistor that limits the amount of current flowing through the LED. For 5.0 V operation, a 2700 resistor will limit the drive current to about 1.4 mA. Where high-speed actuation is desirable, use a lower value resistor for R1. An additional RC peaking circuit is not required with the LH1526 relay. R2 is an optional pull-up resistor which pulls the logic level high ouput (VOH) up toward the VS potential. The pull-up resistance is set at a high value to minimize the overall current drawn from the VS. The primary purpose of this resistor is to keep the differential voltage across the LED below its turn-on threshold. LED dropout voltage is graphed vs. temperature in the Typical Performance Characteristics section. When the logic gate is high, leakage current will flow through R2. R2 will draw up to 8 mA before developing a voltage potential which might possibly turn on the LED. Many applications will operate satisfactorily without a pull-up resistor. In the logic circuit in Figure 1 the only path for current to flow is back into the logic gate. Logic leakage is usually negligible. Each application should be evaluated, however, over the full operating temperature range to make sure that leakage current through the input control LED is kept to a value less than the minimum LED forward current for switch turn-off specification.
