Description
The LH1525 relay is an SPST normally open switch (1
Form A ) in small-outline package (SOP 8 pin). Relay
requires a minimal amount of LED drive current to
operate, making relay ideal for battery powered and
power consumption sensitive applications.
The relay is constructed using a GaAlAs LED for actu-
ation control and an integrated monolithic die for the
switch output. The die, fabricated in a high-voltage
dielectrically isolated BCDMOS technology, is com-
prised 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.

high temperature or high-load current operations,
more LED current is required.

Thermal Considerations
To minimize thermal resistance, pins 6 and 7 of the
LH1525ACD are formed into a tab. This tab should be
soldered to a printed circuit board land pattern of

Functional Description
Figure 2 shows the switch characteristics of the relay.
The relay exhibits an ON-resistance that is exception-
ally linear through the origin and up to the knee cur-
rent (IK). Beyond IK, the incremental resistance
decreases, minimizing internal power dissipation.
Overload currents are clamped at ILMT by the internal
current-limit circuitry. The current-limiting circuitry
exhibits a negative temperature coefficient, thereby
